1. The number of cups of orange drink that ASB would need to sell to reach their goal of raising $240 after selling 60 cups of lemonade is 40 cups.
2. To raise $2,500, the equation representing the scenario is 2L + 3D = 2,500.
3. Rewriting the equation from part 2 above to express the number of orange drinks as a function of the number of lemonade drinks is F(D) = (2,500 - 2L)/3.
What is a mathematical function?A mathematical function is a mathematical expression, rule, or law, defining the value relationship between the independent variable and the dependent variable.
For instance, when we state that the number of orange drinks is a function of the number of lemonade drinks, it means that the number of orange drinks to be sold depends on the number of lemonade drinks sold.
Data and Calculations:Lemonade Orange Drink
Selling price per cup $2 $3
Expected total revenue = $240
Number of cups sold 60
Total revenue $120 ($2 x 60) $120 ($240 - $120)
Number of cups to be sold 40 ($120/$3)
2. The equation is:
2L + 3D = 2,500
Where:
L is the number of Lemonade
D is the number of Orange drinks sold.
3. The rewritten equation is:

For a fundraising project, your math club is publishing a calendar. The cost of the digital images and the permission to use them is $125. In addition to these “one time” charges, the unit cost of printing each calendar is $3.25.
Part a: Write an equation for the total cost of the calendars.
Part b: Write a model that gives the average cost A per calendar as a function of the number of calendars printed.
Part c: Use the graph of the model shown below to estimate the number of calendars that must be sold before the average cost drops to $5 per calendar.
The require answers are,
Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350
Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x
Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
Cost of the digital images and the permission = $125
“one time” charges = $3.25
Part a: The equation for the total cost of the calendars
THere are 100 calendars printed.
So, “one time” charge = 3.25*100
So, the total cost of the calendars C is given as,
C = 125 + 3.25*100
C = 125 + 325 = 450
Thus, the equation for the total cost of the calendars is given as,
C = 125 + 3.25*100 = 450
Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed
Let there are x calendars printed
Total “one time” charges = 3.25x
So, Average cost is given as,
A = 125 + 3.25x
this is the model that gives the average cost A per calendar
Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar
Now from the graph it must be seen that the average cost drops to $ 5 per calender at 70.
Thus, number of calendars that must be sold before the average cost drops to $5 per calendar = 70
Thus, the require answers are,
Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350
Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x
Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.

Jessie baked p cupcakes on Saturday. She baked (p + 3) more cupcakes on Sunday than on Saturday. She baked 30 cupcakes altogether. How many cupcakes did Jessie bake on Saturday?
Answer:
9 cupcakes on Saturday
Step-by-step explanation:
(p + 3) more than p is p + p + 3 = 2p + 3
on Saturday she baked p
on Sunday she baked 2p + 3 , then
p + 2p + 3 = 30
3p + 3 = 30 ( subtract 3 from both sides )
3p = 27 ( divide both sides by 3 )
p = 9
She baked 9 on Saturday and 21 on Sunday

Explain how the substitution method of solving a system of equations differs from the elimination method.
Substitution method of solving a system of equations replaces the variable with a value while elimination method of solving a system of equations removes the variable from the equations.
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
example:
Given two equations: x + 3y = 7 and 2x - 4y = 24, find the solution.
Using substitution method, express one equation to an equation of one of its variables(in terms of the other variable).
x + 3y = 7 ⇒ x = 7 - 3y
Substitute it to the other equation and solve for y.
2x - 4y = 24
2(7 - 3y) - 4y = 24
14 - 6y - 4y = 24
-10y = 10
y = -1
Substitute the value of y in any of the equations and solve for x.
x = 7 - 3y
x = 7 - 3(-1)
x = 7 + 3
x = 10
Hence, the solution is (10 , -1).
Using elimination method, multiply the first equation by 2 so that if we add or subtract it to the second equation, a variable will be removed.
x + 3y = 7 ⇒ 2x + 6y = 14
Subtracting equation 2 from equation 1,
2x + 6y = 14
2x - 4y = 24
0x + 10y = -10
y = -1
Substitute the value of y in any of the equations and solve for x.
x + 3y = 7
x + 3(-1) = 7
x = 7 + 3
x = 10
Hence, the solution is (10 , -1).

Suppose 31 % of Americans recycle. If two Americans are chosen randomly from a group of 50 , what is the probability that at most one of them recycles?
about 90.4% 20 is the probability that at most one of them recycles.
In statistics, what does a probability mean?
The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.P( one) = p ( 1 only ) + p ( 2nd only) + p ( neither)
= ( 0.31) ( 0.69) + ( 0.69 )( 0.31) + ( 0.69) ( 0.69)
≈ 0.9039
So, the probability that at most one of them recycles is about 90.4%.

What is meant by Binomial distribution?In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p. The probability of observing x successes in N trials is calculated using the binomial distribution, with p standing for the probability of success on a single trial. According to the binomial distribution, p is fixed throughout all trials.
The probability of success raised to the power of the number of successes and the probability of failure raised to the power of the difference between the number of successes and the number of trials are multiplied to create the binomial distribution. In mathematics and statistics, the binomial distribution is the likelihood that a specific outcome in a series will occur when there are only two possible outcomes: success or failure. Bi is the prefix for two.
Use the formula for the mean for the Binomial Distribution: μ = np
• n = 16
• p = ½
Therefore μ = 16 × ½ = 8
The mean number of heads is 8.
