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?

Knowing that the current tax of US is 10% in year 2016, Liz's change will be $3.24 round off. in calculation the amount of the CD cost around $15.24 multiply it by 10% tax you'll get $1.52 round off, add the $1.52 to the amount of the CD you'll have $16.76 round off.

Since it already says 15.24 is including tax 20.00 - 15.24 = 4.76
