Question 429137
Heavy Lifting charges an $80 fee plus $40 per hour.
 Quick Move charges $50 per hour with no additional fees.
 Both companies bill for fractional hours.
:
a. Which mover provides a better deal for 3 hours of work? How did you arrive at your answer?
H.L: 3(40) + 80 = $200
Q.M: 3(50) = $150
:
b. Which mover provides a better deal for 15 hours of work? How did you arrive at your answer?
H.L: 15(40) + 80 = $680
Q.M: 15(50) = $750
:
c. For what values h (hours) does Quick Move offer the better deal? Express your answer as an inequality
let h = no. of hrs for this to be true
:
 Q.M. < H.L.
50h < 40h + 80
50h - 40h < 80
10h < 80
h < {{{80/10}}}
h < 8 hrs
For a move less than 8 hrs, Q.M. is cheaper. (at 8hrs, they are the same)
