Question 211654: A stamp collection consists of 8-cent, 13-cent, and 18-cent stamps. The number of 8-cent stamps is twice the number of 18-cent stamps. There are 3 more 13-cent stamp than 18-cent stamps. The total value of the stamps in the collection is $3.68. Find the number of 8-cent stamps in this collection.
I tried letting
X = 18-cent stamps
2x = 13-cent stamps
X+3 = 8-cent stamps
There's a similar problem on the site, but I can't make it work for my own problem. I keep getting decimal answers, when I think it should be whole numbers (number of stamps; you can't really have a fraction of a stamp).

Question 212352: I am looking for help in solving a question from a text concerning the equilibrium point of the problem.
Here is the problem.
Supply and Demand. The supply and demand for the sale of stereos by Sound Ideas are given by S(x)=e^x and D(x)=162,755e^-x, where S(x) is the price at which the company is willing to supply x stereos and D(x) is the demand price for a quantity of x stereos. Find the equilibrium point.
I understand that this is the point that when graphed would be the intersection. My problem is setting up the problem as an equation and then solving it. I thought it would be e^x= 162,755e^-x but I am totally confused on how to treat the e, and how do I solve for x?
