Question

A store is selling all toaster ovens at 15% off
Part A
Write an equation in the form y = kx to represent the sale price y in dollars of a toaster with an original retail price of dollars.
Part B
Find the amount Jill paid for a toaster with an original retail price of $40.

Answer 1

part A) the amount discounted is 15% of the original price. as a decimal, this is 0.15 * the original price.

so: sale price = original price - (0.15 * original price), fill in the appropriate variables/quantities from the problem, and simplify the equation

part B) plug in x = 40 into your equation
