Question 206985
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 > (-30)/(-.3)}}} ------> m > 100


Therefore, in order for Basic Rental to have a better deal than Roadrunners, 

the renter has to rent for MORE THAN {{{highlight_green(100)}}} 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
