A business owner spent $4000 for a computer and software. For bookkeeping purposes, he needs to post the price of the computer and software separately. The computer costs 4 times as much as the software. What is the cost of the software?

Let c be the cost of the computer and s be the cost of the software. We have two equations:
  1. c + s = 4000
  2. c = 4s
Substitute (2) into (1)
(4s) + s = 4000

Using our equation solver, we get s = 800.

Substitute this into Equation (2), we get:
c = 4(800)
c = 3,200
