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.
A) C(n)= 0.25n - 0.75
B) C(n)= 0.75n - 0.25
C) C(n)= 1.0n
D) C(n)= 0.75n
(With solution steps, please. No worded explanation, please.)
The cost of n pieces of candy at $0.75 each is 0.75 * n = 0.75n.
Using the coupon for $0.25 off, we subtract 0.25 from the total cost: 0.75n - 0.25.
Therefore, the correct function rule for the cost of n pieces of candy is B) C(n) = 0.75n - 0.25.
step by step solution please
1. The cost of one piece of candy is $0.75.
2. To find the cost of n pieces of candy, we multiply the cost of one piece ($0.75) by n: 0.75 * n = 0.75n.
3. We have a coupon for $0.25 off our total purchase.
4. To apply the coupon, we subtract $0.25 from the total cost of the n pieces of candy: 0.75n - 0.25.
Therefore, the function rule for the cost of n pieces of candy is C(n) = 0.75n - 0.25.
step by step math equation solutions
Sure! Here are the step-by-step math equations:
1. The cost of one piece of candy is $0.75.
Candy cost = $0.75
2. To find the cost of n pieces of candy, we multiply the cost of 1 piece ($0.75) by n:
Candy cost for n pieces = $0.75 * n
3. We have a coupon for $0.25 off our total purchase.
Coupon value = $0.25
4. To apply the coupon, we subtract $0.25 from the total cost of the n pieces of candy:
Total candy cost with coupon = ($0.75 * n) - $0.25
Final equation:
C(n) = 0.75n - 0.25
Therefore, the function rule for the cost of n pieces of candy is C(n) = 0.75n - 0.25.
