Question

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?

Answer 1

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!

Answer 2

Liz should get back $4.76
$20
-$15.24
=$4.76

or $4.76+$15.24=$20
