Question

Ashley is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges
$
103

and allows unlimited mileage.
Company B has an initial fee of
$
75

and charges an additional
$
0.80

for every mile driven.
For what mileages will Company A charge less than Company B?
Use
m

for the number of miles driven, and solve your inequality for
m

.

Answer 1

y(A)=91

y(B)=55+ 0.90 m 

for what m will y(A)=y(B)? 

y(A)=y(B) 
91=55+0.90m 
0.90m= 36 
m=40 

company B is better if the distance is < 40 miles 
company A is better if the distance is > 40 miles 

for what m is y(A) greater or equal to y(B)?? 
0<m _< 40
