Question

Trina earns $28.50 tutoring for 3 hours. Write an equation relating her earrings "m" to the number of hours "h" she tutors. Assuming the situation is proportional, how much would Trina earn tutoring for 2 hours? For 4.5 hours?

Answer 1

If Trina earns $28.50 in 3 hours, that means she earns $9.50 per hour.

9.50h = m ---> earnings = 9.50 x hours

2 hours = 9.50 ( 2) = $19

4.5 hours = 9.50 ( 4) = $42.75
