Astudent purchases school supplies at a store where the sale tax is 7%. the pre-tax price of the supplies is $48. what is the total cost of the supplies?

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
