I'm confused on how to solve this worded problem
the question is:
to earn extra money, martin works part-time in a butchers shop. In a particular week during the school holidays he worked twice as many hours on tuesday as he did on monday but only 3/4 the hours on wednesday compared to monday. for these three days he received $127.50. if he is paid $8.50 per hour, how many hours did martin work on monday?
