Question

$1,500 computer; 7% tax

Answer 1

Tax sucks, trust me. Since we use tax often in our lives, it's quite easy nowadays.

Switch the 7% tax to a number that can be used in a calculation. 
Always divide the percent (7%) by 100%. 
7% divided by 100% = 0.07

Now, you need to find out the total cost. 
Always multiply 0.07 by 1500. 
0.07 × 1500 = 105.

Now that we know that you have to pay an extra $105 tax, we can add it with the original price. 
$1500 + 105 = 1605.

Your total price for the computer will be: $1605.

Answer 2

You would have to find 7% of $1,500. 
7% = 0.07
1,500 x 0.07 = 105
105 + 1,500 = 1,605
The computer cost (with tax added) $1,605.
