Answer 1

A

Explanation:

Your answer will actually be A.

He received a refund of 245.75$, and then he purchased the bass guitar. Since the bass guitar is worth more than the acoustic guitar, he didn't pay the full price. He has 122.70$ left to pay.

Answer 2

A. The sum 245.75 + (–368.45) = –122.70 means that Robbie still owes $122.70 for the bass guitar.

Explanation:

Since Robbie returned a guitar that cost $245.75, he will be recieving a positive amount of money, being a gain of money; then he decides to buy a bass guitar, which costs $368.45, which makes it a loss of money, thus A would be the correct answer.
