Question

to earn extra money, martin works part-time in a butcher's 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 3 days he received $127.50. if he is paid $8.50 per hour, how many hours did martin work on monday?

Answer 1

x = monday
2x = tuesday
3/4 x = wednesday

8.50x + 8.5(2x) + 8.5(3/4x) = 127.50
8.50x + 17x + 6.375x = 127.50
31.875x = 127.50
x = 127.50 / 31.875
x = 4

Martin worked for 4 hours on Monday.
