Answer:
Michael worked for 5.5 hours.
Step-by-step explanation:
Total money earned = $74.25
Money Earned in tips = $38.50

Total money he earned is equal to Cost per hour multiplied by number of hours he worked plus money earned in tips.
Hence;
Cost per hour × number of hours he worked + Money Earned in tips = Total money earned
Computing in mathematical form we get;
Hence Micheal worked for 5.5 hours.
Answer:

-4x = 10/3
x = -40/3
