The expression which shows the saving is 40 + 40 and 40 x 2. The correct options are C and D.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the amount of money saved by Erica is $40. The expression which represents the savings will be,
40 + 40 = 80
40 x 2 = 80
Therefore, the expression which shows the saving is 40 + 40 and 40 x 2. The correct options are C and D.

Jose interviewed for two different sales positions at
competing companies. Reliable Robotics has offered
Jose a salary of $31,200 per year plus a 9%
commission on his total sales. Robot Renegades offers
him $26,000 per year salary plus a 15% commission on
total sales for the year.
Write two linear equations, one for each offer, for the
annual pay y that Jose can make based on weekly
sales x.
Jose isn't sure which offer to accept. He likes both
companies so it comes down to the better offer. Jose is
pretty sure he can make at least $2000 sales a week.
Recommend to Jose which job he should take
considering his estimation of $2000 a week.
Answer:
Reliable Robotics: .09x+31200
Robot Renegades: .15x+26000
If Jose does 2000 sales a week this means that Robot Renegades is the better offer
Step-by-step explanation:
Reliable Robotic's offer can be modeled through the following equation
.09x+31200
And for robot renegades it's
.15x+26000
If we plug in 2,000 and multiply by 52 (to see how many sales he makes a year) into x we get
.09*2000*52+31200=40560
.15*2000*52+26000=41600
This obviously means that reliable robotics is the better offer

Simplify: 4(36)?????
Answer:
To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF). So, 436 = 4÷436÷4 = 19. Thus, 436 is equivalent to 19 in the reduced form.
Step-by-step explanation:
The solution for the expression 4(36) after you simplify can be expressed as 144.
What is 4(36) when you simplify?To simplify the expression 4(36), we need to perform the multiplication operation.
4 multiplied by 36 can be calculated as follows:
4 x 6 = 24 (multiplying the units digit)
4 x 30 = 120 (multiplying the tens digit)
Now, we add the results together:
24 + 120 = 144
Therefore, the number 4 multiplied by the number 36in brackets is equals to 144.

Answer:
1/3 of 3/5 = 1/5
Step-by-step explanation:
She had 3/5 pan of crispy rice treats and sent 1/3 of the treats to school.
The fraction of the whole pan that she sent to school will be calculated by
1/3 of 3/5
= 1/3 * 3/5
=1*3/3*5
= 3/15 = 1/5

Answer:
a = 14
b = 15
c = 15
d = 18
e = 18
Step-by-step explanation:
The stratified sampling works as follows:
stratified sampling = (Population of subgroups)*(total sample size)/(entire population)
in this case, sample size = 80
entire population = 140 + 150 + 150 + 180 + 180 = 800
Population sample is the number of students of each year (for year 7, the population of subgroup is 140, and so on)
whith this equation we can find all the missing values:
a = (140)*(80/800) = 14
b = (150)*(80/800) = 15
c = (150)*(80/800) = 15
d = (180)*(80/800) = 18
e = (180)*(80/800) = 18
About \frac{3}{8}3 8 of the business calls that Ms. Rodriguez makes are long distance calls. How many business calls would you expect her to make in a month when she makes 32 long distance calls? Write an equation to find the total number of calls Ms. Rodriguez makes in a month.
[tex]\frac{3}{8}x = 32[/tex]
multiply both sides by the reciprocal
x = 85⅓
We would expect her to make about 85 business calls in a month.
Step-by-step explanation:
The equation means "3/8 of the unknown total is 32"
When we multiply 3/8 by its reciprocal, it becomes 1 and cancels on the left.
8/3 times 32 is a mixed number, so it is reasonable to round it to a whole number of calls.
