Solution: We are given:
Sales tax
The pre-tax price of the supplies
We have to find the total cost of the supplies.
We first need to find the sales tax on the price of supplies. The sales tax amount is:
Therefore, the total cost of the supplies = pre-tax price of the sales + sales tax amount
=$48 + $3.36
=$51.36
c(x) is a function, then we will solve the problem for two different functions.
1. If
Then
Using each of the values for x we have.
When x=0 the result is:
When x=0.008 the result is:
When x=0.027 the result is:
When x=0.064 the result is:
When x=0.125 the result is:
When x=0.216 the result is:
When x=0.343 the result is:
When x=0.512 the result is:
When x=0.729 the result is:
When x=1 the result is:
