Topic 5 Equations/Inequalities Practice Test

Moesha needs $79 for a class trip. She already has $22 and she can earn the rest by babysitting for 8 hours. If h represents her hourly earnings, which of the following equations can be solved to find Moesha’s hourly earnings? Select all that apply. (2 answers)

• 79 = 22h + 8

• 79 - 22 = 8h

• 79 = 22 + 8h

• 22 = 79 - h

• 79 + 22 = 8h
