The cost of a CD at Ernesto's Music Emporium is $12, including tax. Brian has a $100 gift card from Ernesto's. What is his balance after he buys 4 CDs?

Respuesta :

COST OF CD'S
12 x 4 = 48

GIFT CARD BALANCE
100 - 48 = 52

Therefore the balance of his gift card is $52 after he purchases 4 CD's
I think 52 because its 2 tax on each cd
