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?

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

or $4.76+$15.24=$20

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!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
