Question

Max purchased a professional headphone online. He paid $149.75. This amount included a 7% sales tax. What was the price of the headphone itself?

Answer 1

$139.95

Explanation:

The price of the headphone was LESS THAN 149.75, of course.

Let original price of headphone be x

So we can say:

x PLUS a 7% sales tax on top of that gives us 149.75

Note: 7% means 0.07

So we can write:

x + 0.07 (x) = 149.75

x + 0.07x = 149.75

1.07x = 149.75

x = 149.75/1.07

x= 139.95

Thus, the headphone's original price is around $139.95
