Question 189669
Heavy Lifting charges 80+35*h
Quick Move charges 55*h

You want to find h (hours) where:

80+35h>55h (Heavy Lifting charges more than Quick Move)

Subtracting 35h from both sides, we get:

80+35h-35h>55h-35h
80>20h

Dividing bothsides by 20, we get:

4>h

So Quick Move is cheaper/better deal if h is less than 4 hours
