The cost of the computer is: $550

The additional tax is: 10.2%

To find the final cost of the computer, first, we need to find how much is the tax of 10.2%.

Step 1. Calculate how much is 10.2% of $550.

In general, to calculate a percentage we divide the quantity by 100 and then multiply by the percentage we need. In this case:

[tex]\frac{550}{100}\times10.2[/tex]

Solving the operations:

[tex]5.5\times10.2[/tex][tex]=56.1[/tex]

The tax is $56.1

Step 2. Add the cost of the computer and the tax to find how much he paid for the computer:

[tex]550+56.1=606.1[/tex]

Answer: $606.1
