Problema Solution
sally earns $5.50 per hour and adam earns $3 per hour. they each earn the same amount each week but adam works 4 more hours. how many hours a week does adam work?
Answer provided by our tutors
let 'W' represent weekly salary and 'h' represent the number of hours Adam works, therefore 'h-4' represents the number of hours Sally works
Sally's weekly salary:
W = 5.50(h-4)
Adam's weekly salary:
W = 3.00h
we set the two salaries equal to each other:
5.50(h-4) = 3.00h
solving for 'h' we have h=8.8
Adam works 8.8 hours each week
