3. Moving Costs
Moving company A charges $80 plus $55 an hour to move households across town. Moving Company B charges $75 an hour for crosstown moves. For what lengths of time is Moving Company B more expensive than Moving Company A? Write an inequality and solve for time t.
Show your work not just the final answer.

I am not inclined to show work for someone to copy.
costeach= costperhour*time + fixedcost
In one, the fixed cost is zero.
find time when both are equal (set the two cost equations equal to each other).
then, for times greater than that, Company B is costlier, and for times less than that, Company A is costlier. 
Iam wanting help i do not want you to do it for me. I just needed it broken down in order to answer Thank you for your help.

A:
80 + 55 + 55 + 55 + 55
B:
75 + 75 + 75 + 75 
Thank you for you answer Ms Sue.
