turn 20% into a decimal then multiply by 72.50. What do you get?

OpenStudy (study312):

0.20 • 72.50 = ?

14.5

OpenStudy (anonymous):

?

OpenStudy (study312):

now 72.50 - 14.5 = ?

OpenStudy (anonymous):

58?

OpenStudy (study312):

Yes! now 58 • 0.15 = ?

OpenStudy (anonymous):

8.7?

OpenStudy (study312):

Yup. Now finally 58 - 8.7 = your final answer

OpenStudy (anonymous):

I got 49.3
