Question

Deshaun 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 and allows unlimited mileage.
Company B has an initial fee of and charges an additional for every mile driven.
For what mileages will Company A charge less than Company B?
Use for the number of miles driven, and solve your inequality for m

Answer 1

need to see the prices

Answer 2

@texaschic101
a charges 86
b charges 65 with a additional .70 for every mile driven

Answer 3

86 < 65 + .70m
86 - 65 < .70m
21 < .70m
21/.70 < m
30 < m

Company A charges less then company B if the miles are less then 30.

lets check...
86 < 65 + .70(29)
86 < 65 + 20.3
86 < 65 + 20.3
86 < 85.3 (correct)

Answer 4

any questions ?

Answer 5

How did you decide the way to set it up? Excuse me please, I am terrible at math :/ I try to only post the ones that completely fool me

Answer 6

Answer 7

I set up company A < company B
Company A charges 86
Company B charges 65 + .70m
so it is set up like :
86 < 65 + .70m and just solved for m
I then checked it and it came to be true
Does that help ? I am not the best at explaining
