Answer:
B. C(n)=0.75n-0.25
Step-by-step explanation:
Given : Cost of one candy = $0.75
There is a coupon of $0.25 off on total purchase .
To Find : Write a function rule for the cost of n pieces of candy.
Solution :
Since we are given that total candies bought = n
Cost of one candy = $0.75
Cost of n candy = $0.75n
So, cost of total purchase = $0.75n
Since on total purchase there is a off of $0.25
So, cost of total purchase after off will be $0.75n -$0.25
⇒C(n)= 0.75n-0.25
Where C(n) denotes the total cost after getting off
Hence Option B is correct.
A function rule for the cost of n pieces of candy is C(n)= 0.75n-0.25
