Liz wants to buy her favorite musical group's new CD. The CD costs $15.24, including tax. Liz gives the store clerk a twenty-dollar bill. How much change should Liz get back?
Let x represent the money that Liz should get back x+15.24=20.00 Subtract 15.24 to each side x+15.24-15.24=20.00-15.24 x=$4.76. As a result,Luz should get $4.76 back as the change. Hope it help!
