keiko is getting to rent a truck for one day. there are two companies she can choose from , and they have the following prices. company A charges $73 and allows unlimited mileage.company B has an initial fee of $55 and charges an additional $0.90 for every mile driven for what mileages will comany A charge less than company B? use M for the number of miles driven, and solve your inequality for m.

Respuesta :

Let

y ---> total charge

m ---> number of miles

so

Company A

y=73 ------> equation A

Company B

y=0.90m+55 ----> equation B

Company A < Company B

The inequality that represents this situation is equal to

73 < 0.90m+55

solve for m

73-55 < 0.90m

18 < 0.90m

Rewrite

0.90m > 18

m > 20 miles

the number of miles must be greater than 20 miles
