Answer:
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
[tex]=\frac{15}{100}x[/tex]
=0.15x
Now, sale price = original cost - discount
[tex]\Rightarrow y = x-0.15x[/tex]
[tex]\Rightarrow y=0.85x[/tex]
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,[tex]y=0.85\times 40=34.[/tex]
Hence, Jill paid $34 for a toaster.
