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.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
