Question

a person bought 8 items at a market and received $8 in change. if each item was priced at $4, how much did the person give the vendor when paying?

Answer 1

If a person bought 8 items and each item was priced at $4, that means the total amount spent was $32.

`(8)(4)=32`

The person received 8 dollars in change. This means that the person payed 8 dollars more than what they spent. Well, we just found out how much they spent, so we can find out how much money the person gave the vendor.

Let p = amount of money paid by the person.

`32+8=p`

`p=40`

The person gave the vendor $40.
