Answer:
Purchase amount = $642
Explanation:
Given that:
Jeff has bought:
cell phone = $500
4 Accessories = 4 * $25
4 acessories = $100
Total = $500 + $100 = $600
As the sale tax is 7% so
Sale tax = 7% (600)
Sale Tax = 0.07(600)
Sale Tax = $42
So the purchase amount will be Total + Sale Tax
Purchase amount = $600 + $42 = $642
