Question 1121686
<font face="Times New Roman" size="+2">


The total cost to rent the first car for *[tex \Large m] miles is *[tex \Large 20\ +\ 0.5m].  The total to rent the second car for *[tex \Large m] miles is *[tex \Large 30\ +\ 0.25m].  You want to know *[tex \Large m] when these two amounts are equal.  So set the two expressions equal to each other and then solve for *[tex \Large m]
