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

y=0.85x

Jill paid $34 for a toaster.

Step-by-step explanation:

Given that, x and y are the original cost and the sale price of the toaster oven after discount.

As there is 15% off on the original cost, so,

the discount amount = 15% of x

=0.15x

Now, sale price = original cost - discount

This is the required equation in the form of y=kx, where k=0.85.

If the original cost of the toaster is $40.

Then the sale price,

Hence, Jill paid $34 for a toaster.
