Thanks!

So, in response to my previous post.. I was on the right track.

(1400)(961400)+(30593)(9200)

which equals: 1627415600

And that is the solution to your problem :) 

With Newtons law of Universal Gravitation!

2x where x is the number of dollers you get?

Thank you! :)

Differentiation (aka, derivatives).

Your question is worded kind of poorly..

"If you get a doller for every doller you get"

kind of sounds like you'll only get one doller.. if you're trying to say 

"you're given an extra doller for every doller you get"

then that's an entirely different thing.. 

I solved it. The solution is y=-3x 

(as b=0)

Thanks all for the help.

I'm not sure that this answer is right (at least in the terms that OP was reffering to). The product rule for derrivatives is 

derivative of fg = fg' + f'g

I *think* the two functions given in the equation would be:

p(t) = 961400+9200t

a(x) = 30593+1400t

p'(t) = 9200

a'(t) = 1400

so the derivative of pa is = pa' + p'a

Okay, but what would the equation of the line be in y=mx+b form?
