A movie theater sends out a coupon for 25​% 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.

The equation is y =__
​(Use integers or decimals for any numbers in the​ expression).

Answer 1

Explanation:

x-the original price

y- the discounted price

y= the original price - 25 % discounted from x = x- (.25*x) = x( 1-.25) = .75x

equation is y= .75x

The equation should only be in the first quadrant because the prices can only be positive numbers.
