(Q12) Javier and his brother David both got summer jobs. Last week Javier saved $20 and he earns $9 per hour at his part-time job. David saved $15
last week and makes $10 per hour at his part-time job. Which equation can
be used to find the number of hours, h, it will take for Javier and David to
earn the same amount of money at their new jobs?
9h + 20 = 10h + 15
20h + 9 = 15h + 10
O 29h = 25h
9h - 20 = 10h - 15
