Answer 1

Well first make an equation for each person

Answer 2

Okay I'd appreciate if you would walk me through it

Answer 3

Since Tom has 30 CDs you know that the end of the equation will have a +30

Answer 4

okay

Answer 5

and the same goes for nita the end of her equation would have a +18

Answer 6

@cutiecomittee123 are you still helping?

Answer 7

Sorry I had to go to my own question, but sure Ill try. So now that you have the constants, you are going to need to put in a change. What types of equations are you learning in school right now? like what math are you in?

Answer 8

It would help to know that in order to get a basis for what the equation is supposed to be set up as.

Answer 9

This is my algebra exam

Answer 10

@kitteh♥ lol could you help please?

Answer 11

Oh yikes, So are we just using geometric or arithmetic equations?

Answer 12

If M was equal to one month then I think you could write their equations like so;
Nita: y=5m+18
Tom: y=m+30

Answer 13

Im not 100% sure but that is what I am guessing will help you.

Answer 14

I got this equation:y=2x+30
y=4x+18

Answer 15

So it would take 2 months
