Question 674044: I need help solving this problem:
a couple wishes to rent a car for one day while on vacation. ford automobile rental want $26 per day and $0.16 per mile, while chevrolet for a day wants $23 per day and $0.18 per mile. after how many miles would the price to rent the chevrolet exceed the price to rent a ford?
Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
Let x be the number of miles
Ford 26 + 0.16 x
chevrolet 23 + 0.18 x
Ford > chevrolet
26 + 0.16 x > 23 + 0.18 x
add -26 to both sides
26+0.16n-26>23 +0.18x-26
0.16 n- -23 > > 0.18 x -3
add -0.18 x
-0.02 x > -3
/ -0.02
x < 150
x should be less than 150 for Ford to be a better deal
OR Chevrolet will be expensive after 150 miles
