Amovie theater sends out a coupon for 10% off the price of a ticket. write an equation for the situation, where y is the price of the ticket with the coupon, and x is the original price of the ticket. use pencil and paper. draw a graph of the equation and explain why the line should only be in the first quadrant. the equation is y =

y = 0.9x

Step-by-step explanation:

A movie theater sends out a coupon for 10% off the price of a ticket, so the price of the ticket with the coupon is 100% - 10% = 90% of the original price.

Let

x = original price

y = price of the ticket with the coupon

Then

x - 100%

y - 90%

Write a proportion:

Cross multiply:

Since the original price and final price are always greater than 0, then the graph of this equation is in the first quadrant (see attached diagram)

do you mean add both of the equations together

because if you do the answer is 10x-5
