109.31

To find this you can convert 58% to decimal form, which is .58. Once you have a decimal form of a percent, you can multiply it by the number you are taking the percent of and get an answer. So .58 times something equals 63.4. You can write this as an equation:

.58x = 63.4

and solve for x, which would get 63.4/.58, which equals 109.31.

To solve this problem you must apply the proccedure shown below:

1. You must make a system of equation by using the information given in the problem above. Then, let's call:

$x$ : The number of computers sold.

$y$ : The number of hard drives sold.

2. Therefore, you have the following system of equations:

$\left \{ {{x+y=36} \atop {1180x+125y=30875}} \right.$

2. Solve for $x$ in the first equation and substitute it into the second equation:

$x=36-y\\ 1180(36-y)+125y=30875$

3. Solve for $y$ :

$42480-1180y+125y=30875\\ y=11$

4. Substitute the value of $y$ into the first equation to calculate $x$ :

$x+11=36\\ x=25$

Therefore, the answer is: The store sold $25$ computers and $11$ hard drives.
