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.

$\frac{5s}{5} = \frac{4000}{5}$

Simplify to obtain,

$s = 800$

Hence the cost of the software is $800
