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. (1 point) Responses C(n) = 0.25n – 0.75 C ( n ) = 0.25 n – 0.75 C(n) = 0.75n – 0.25 C ( n ) = 0.75 n – 0.25 C(n) = 1.0n C ( n ) = 1.0 n C(n) = 0.75n C ( n ) = 0.75 n
C(n) = 0.75n - 0.25
tell me the steps of this answer
To find the function rule for the cost of n pieces of candy, you need to consider the price per piece of candy and any discounts or coupons applied to the total purchase.
1. Start with the price per piece of candy, which is $0.75.
2. Next, consider the coupon for $0.25 off your total purchase. This means that for every purchase, you can subtract $0.25 from the total cost.
3. To represent the total cost of n pieces of candy, you need to multiply the price per piece ($0.75) by the number of pieces (n) and subtract the coupon amount ($0.25). This gives you the function rule: C(n) = 0.75n - 0.25.
So, the correct answer is C(n) = 0.75n - 0.25.
