Question

You need to rent a moving truck for a day. You have identified two companies that rent trucks company A charges $50 per day plus $0.10 per mile. Company B charges $20 per day plus $0.20 per mile. For how many miles will the cost of renting be the same?

Answer 1

A=50+0.10m
b=20+0.20m

50+0.10m=20+0.20m then you move the 20 over
30+0.10m=0.20m the  you move the 0.10m over
30=0.10m then move the 10 over again
=300m
