Frank 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 $93 and allows unlimited mileage. Company B has an initial fee of $65 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 @KaMaddie

let me take a look
okay lets write an equation for how much A will cost
can u show me how its supposed to be solve,
how abouuuuuuuuuttttt. COST=93
yes i will show you
next lets write an equation for B
COST=65+.7m
ok how
you pay .7 for the miles you drive so we want to multiply our miles by .7
what do i put then
and the 65 just gets added on
now we want to see when A is less than B
A < B
well now we know what A and B are A is 93 and B is 65+.7m
so why don't you plug them in to A<B and see what you get
so how its solved
no, for now just take 93 and 65+.7m and put them into our A<B
how will it be writtrn
yes
you tell me
|dw:1416341068925:dw|
93<65+.7m
awesome, now can you do some work to get M by itself?
lets start by moving that 65 to the other side. how do we do that?
idk how, i got a minute left for the right answer
93-65<.7m 28<.7m 28/.7<m 40<m
is it 40<m
when the miles are greater than 40 you are paying less for A
m>40
can u help with this one For his phone service, Hong pays a monthly fee of $16 , and he pays an additional $0.05 per minute of use. The least he has been charged in a month is $76.45 . What are the possible numbers of minutes he has used his phone in a month? Use m for the number of minutes, and solve your inequality for m
@camper4834
i'll help you with making the equation but do you know how to do algebra?
yes
i just need help with the equation
okay when i show you how to make the equation i need you to finish it
k i will
so he pays .05 per minute
that means multiply .05 by minutes (m)
then just add 16 to get 16+0.05m
this will get you your cost AND
\[76.45 \le COST\]
so theres not inequality sign
\[76.45 \le 16+0.05m\] solve for m
i have one last one.... To rent a certain meeting room, a college charges a reservation fee of $37 and an additional fee of $9.30 per hour. The film club wants to spend at most $120.70 on renting the meeting room. What are the possible amounts of time for which they could rent the meeting room? Use t for the number of hours the meeting room is rented, and solve your inequality for t
@camper4834
\[(reservation fee) + (additional fee) * (h) \le 120.70\]
