Answer:

$300.

Explanation:

Let x represent original cost of each hard drive.

We have been given that IBM states that it makes a 30% profit over its expenses for producing hard drives.

The cost of each hard drive after profit would be x plus 30% of x.

$\text{The cost of each hard drive after profit}=x+(30)/(100)x$

$\text{The cost of each hard drive after profit}=x+0.30x$

$\text{The cost of each hard drive after profit}=1.30x$

We have been given that IBM sells each hard drive for $390. We can represent this information in an equation as:

$1.30x=\$390$

$(1.30x)/(1.30)=(\$390)/(1.30)$

$x=\$300$

Therefore, the original cost of each hard drive is $300.
