Question

Joan joined her school's band. She bought a viola for $72.21, and a song book

which was $7.25 with a $100 bill. How much change was Joan given?

Answer 1

$100-$72.21-$7.25=$20.54

Answer 2

Hello :D

To do this you need to add the cost of the violin and the song book.

$72.21 + $7.25 = $79.46

$100 - $79.46 = $20.54

The answer is $20.54. I hope this helps :)
