Sam needs to rent a car. He is considering two companies

A+ Auto rental: $175 + $0.10 per mile
Zippy Auto rental: $220 + $0.05 per mile

Solve a system of equations to determine when the rental costs the same for both companies

x will stand for the # of miles
f(x)=175 + .10x
f(x)= 220 + .05x

when x= 900 (900 miles) the rental costs will be the same.
f(x)=175+ .10(900)= 265
f(x)=220 + .05(900)= 265
