Question 404549: Charlie is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges $127 and allows unlimited mileage.
Company B has an initial fee of $55.00 and charges an additional $0.90 for every mile driven.
For what mileages will Company A charge at least as much as Company B? Use m for the number of miles driven, and solve your inequality for m .
my answer-please check me
a=127
b=55+.9m
127=55+.9m
72=.9m
m=80
I'm not sure if the answer should be m>=80 or m<=80

Charlie is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges $127 and allows unlimited mileage.
Company B has an initial fee of $55.00 and charges an additional $0.90 for every mile driven.
----
A(x) = 127x dollars
B(x) = 55 + 0.9x dollars
----
For what mileages will Company A charge "at least as much" as Company B? Use m for the number of miles driven, and solve your inequality for m .
my answer-please check me
a=127
b=55+.9m
Solve: a >= b
127 >= 55+.9m
72 >= 0.9m
m <= 72/0.9
---
m <= 80 miles (a >= b when # of miles <= 80)
