The profit he made from selling his hearing aids at a profit of 17% is $234.26.
<h3>How to calculate the profit obtained?</h3>
To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.
- $1,378 ÷ 100 = $13.78
- $13.78 × 17 = $234.26
Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.
$1,378 + $234.26 = $1,612.26
