The final cost of a sale item is determined by multiplying the price on the tag by 75%. which best describes the function that represents the situation?

It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant is the function that represents best the situation.

For example.

the price tag is 10 dollars, thus the equation would be:

=> 10 (0.75)

=> x (0.75), where x is the price of the sales item.
