Answer 2

On average, Susan downloads 60 songs per month. An online music vendor sells package prices for songs that can be downloaded on to personal digital devices. The graph (attached) shows the package prices for the most popular promotions. Susan wants to know if she should buy her music from this company or pay a flat fee of $58.00 per month offered by another company. Which is the better buy?

a. Find the constant of proportionality for this situation.

Answer 3

Can you please wait until I get the graph on OS?

Answer 4

what is the price when x = 60 from the graph compared with the flat fee with the second company for $58?

Answer 5

This is the graph.

Answer 6

so do you understand what to do with the graph?

Answer 7

Not really because I can't find the constant of proportionality in the graph.

Answer 8

that should just be the slope
I will look at the graph

Answer 9

the other problem was cost per shirt this problem is cost per song = the slope
you are given points on the line (x1, y1) etc
you need to find the cost for x = 60
y = m x + b or you can use point-slope version (y2-y1) = m(x2 - x1)

Answer 10

after you have the cost for 60 songs with company 1 compare that with $58.00 at company 2

Answer 11

you already know the better buy is the lower cost for the same number of songs

Answer 12

@inkyvoyd Can you explain this to me a little further? Because I have no idea what is going on... @triciaal Can you help me more with this too?

Answer 13

o crud you found me I was just kinda idling here x.x

Answer 14

@calculusxy think about the problem we just did
this is the same thing except we have songs instead of shirts
you found that it cost $7 per shirt this time you need to find the cost per song
now you know the cost for 1 song what would be the cost for 60 songs?
this is at company 1

company 2 has the cost for 60 songs is $58

which company will charge less for 60 songs?

let me know exactly where you need more help and we will get through it

Answer 15

I use the same formula right?
m = (y2 -y1)/(x2-x1)
