Question

please help Lauren wants to buy 3 shirts at 15.00 each. At home, she calculates the total cost as 46.20 using the sales tax of 8% . At the store, the cashier tells Lauren the total cost is 48.60 . Who is wrong and what mistake did he or she make ?

Answer 1

Lauren is wrong. Maybe she added incorrectly??

Explanation:

3 * 15 = 45

45 * 8% = 3.60

45.00 + 3.60 = 48.60
