Question

A customer buys four products priced at $18, $22, $35 and $40 from the same store. The customer returns the most expensive product and gets a refund for that one product. How much money did the customer end up spending at that store? $70

Answer 1

18 + 22 + 35 + 40 = 115
So the customer spent $115 and then returned the most expensive ($40) item.

115 - 40 = 75
So after the refund the customer has spent $75.

Hope it helps!

Answer 2

18 + 22 + 35 = 75 <== the customer spent 75
