You have a coupon for 30% off your dinner. Your total bill was $50. You also need to pay a 7% sales tax and leave a 22% tip. With the discount, tip + tax included, how much was your dinner? I am having trouble with this one

Answers

Answer:
$49.50
Step-by-step explanation:
30% of $50 = $15.00
7% of $50 = $3.50
22% of $50 = $11.00
$50.00 - $15.00 = $35.00
$35.00 + $3.50 = $38.50
$38.50 + $11.00 = $49.50
How much was your dinner?
The total amount is $49.50, so only a total of 50 cents is being taken off from the whole payment of the dinner. (≧◡≦) (o´∀`o) (´• ω •`) (＾▽＾) (⌒ω⌒)

The system of equations y=-2x+3 and y=x is graohed. What is the solution to the system of equations

Answers

Answer:

The solution to this system of equations is y = 1, x = 1

Step-by-step explanation:

We know that...

(1) y = - 2x + 3

(2) y = x

Then we just substitute the value of x that we are given in equation (2).

And so we get....

y = -2x + 3

x = - 2x + 3

3x = 3

x = 1

From equation (2) we know that y = x, so since x equals 1 y is also 1. There for the solution to this system of equations is (1,1)

Solve the system by substitution.

y = 2x

3/4 of a foot?

Answers

Answer:

One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?

1 foot - 3 dollars

3/4 foot - x dollars

[tex]x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25[/tex]
