Question

a business owner spend $4,000 for a computer and software for bookkeeping purposes he needs to post the price of the computer and software separately the computer cost 4 times as much as a software what is the cost of the software

Answer 1

Let the cost of the computer be $

`c`
and the cost of the software be $

`s`
The total cost the business owner incurred was $

`4000`
This means that,


`c + s = 4000 - - - (1)`

We were given another information concerning the relationship between cost of the computer and that of the software.

That is, the computer costs 4 times the software.

Mathematically, we express this relation as,


`c = 4s - - - (2)`

Now, we substitute equation 2 into equation 1 to obtain,


`4s + s = 4000`

We simplify to get,


`5s = 4000`

Divide both sides by 5.


`(5s)/(5) = (4000)/(5)`

Simplify to obtain,


`s = 800`

Hence the cost of the software is $800
