Candy is on sale for 0.75 each. You have a coupon for 0.25 off your total purchase. Write a function rule for the cost of n pieces of candy.

Answer 1

The function rule for the cost of n pieces of candy can be written as:

Cost(n) = (0.75 * n) - 0.25

This equation takes into account the cost of each piece of candy (0.75) and subtracts the value of the coupon (0.25 off the total purchase), resulting in the cost of n pieces of candy.
