# 39 on page 36, specifically part a and case 1

http://books.google.com/books?id=mw...e&q=suppose ms lee is buying a house&f=false"

M(0) = $150000 ------>initial amount due

M(30) = $0 -------> final amount due

r = .07

p=?

2. Relevant equations

anything to do with diffe equations

3. The attempt at a solution

Well I don't want to show all the work for it but one can find a general solution to the equation listed in the problem by dividing both sides by rM-p and by multilpying both sides by dt. So

dM/(rM-p)=dt

From here you can integrate and eventually get the general solution of

M = c*e^(r*t)+p/r

With M(0) = 150000 and M(30) = 0 I can solve for both c and p but I seem to be missing something. How do I find out how much she pays? I'm lost. Even by after checking with the answers in the back of the book I can't get the answer that they got.
