Bill wants to rent a car. Rental Company A charges $35 per day plus $0.10 per mile driven. Rental Company B charges $25 per day
vova2212 [387]

After 300 miles.

35+0.1x= 25+0.15x

<u> -0.1x -.01x</u> (0.1- 0.1 crosses out)

35= 25+0.15x

<u> -25 -25 </u> (25- 25 crosses out)

15= 0.15x

15/0.15= 0.15x/0.15 (crosses out)

300= x
