50+.2x+20+.5x
-.3x=-30
.3x=30
x=100 mi

50+.2(100)=20+.5(100)
$70=$70

Since Basic Rental charges $50, plus $0.20 per mile, and since Roadrunners
charges $20, plus $0.50, per mile, then in order for Basic Rental to have a
better rental deal than Roadrunners, we'll have:
50 + .2(m) < 20 + .5(m) (using m for amount of miles)
50 + .2m < 20 + .5m
-.3m < - 30
------> m > 100
Therefore, in order for Basic Rental to have a better deal than Roadrunners,
the renter has to rent for MORE THAN miles
Check:
Since m > 100, we'll use value of 101
50 + .2(101) < 20 + .5(101)
50 + 20.20 < 20 + 50.50
70.20 < 70.50
