Answer:
$139.95
Step-by-step 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
