Mike has earned a total of $160 in wages this week. He received the wages for his first job, then later received the wages from his second job where he works 12 hours a week. If his second job pays $9 per hour then how much money, in dollars, did Mike receive from his first job?
Thoughts? Step-by-step reasoning:
From his second job, Mike receives $9 / hour * 12 hours = $108. He therefore earned $160 $108 = $52 from his first job.
Thus, the answer is 52.
