Answer:
A. Tom made more money than Martin.
Explanation:
We have been given that Tom and Martin both worked 8 hours this week and sold $520 worth of meals. Their hourly wages are $2.15 and $2.50, respectively. In addition, Tom's percent of tips was 15% while Martin's was 12%.
Tom's weekly wages would be his hourly wages times 8 plus 15% of total sales, that is:




Martin's weekly wages would be his hourly wages times 8 plus 12% of total sales, that is:




Since Tom's weekly wages ($95.20) is more than Martin's weekly wages ($82.40), therefore, option A is the correct choice.
