Question

Company A charges $90 and allows unlimited mileage. Company B has an initial fee of $55
and charges an additional $0.70 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.

((show me how you got the inequality and I can solve it from there))

Answer 1

@RCCB

Answer 2

anything? :3

Answer 3

maybe

Answer 4

whatcha got?

Answer 5

well just add .70 to 50 for every mile and when that price goes above 90 then you have your answer

Answer 6

70 to 50? but the first price for b at least is 55 not 50

Answer 7

*0.70

Answer 8

or wait 55 your right sorry

Answer 9

no problemo! now what?

Answer 10

ohmahgawd ima dumbbyyy
you would make the equation of 90m=55+0.70m right? then work it out first then make your inequality

Answer 11

yeah that sounds about right,

Answer 12

50=m

Answer 13

wait its saying charge less hmm

Answer 14

does that make a difference?

Answer 15

one second

Answer 16

ok so you want company b to cost more than company a, you have to find out how many miles it will take to have to pay more at company b,

Answer 17

so you keep adding .70 to 55 until it is over 90, and for every time you add .70 that counts as one mile, so if you add .70 5 times, thats 5 miles.

Answer 18

so would that be 90<55+70(5)?

Answer 19

then would you solve it?

Answer 20

5 was just an example thats not a number that gets used

Answer 21

oooo, but if its more the 90 then wouldn't it be right?

Answer 22

wait, so would the inequality be 90<55+0.70(m) yeah?

Answer 23

add .70 so many times to 55, and keep adding .70 until the total number is above 90

Answer 24

wat

Answer 25

you have 55 right?

Answer 26

yeah

Answer 27

ok and you have to add .70 to it

Answer 28

so you get 55.70

Answer 29

and you would add another .70

Answer 30

oh oh ohh! i getchu now ok

Answer 31

56.40

Answer 32

and you keep doing that until you get that number above 90, does that make sense?

Answer 33

yeah I get it thanks!

Answer 34

haha no problem, but remeber how many times you add .70, then you take that number and that is how many miles driven

Answer 35

that is the millage that company a charges less than company b

Answer 36

haha awesome thanks ! :)

Answer 37

haha no problem :) so you get it?
