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

The answer can then be simplified to
378≤x≤678
Hello there! :D
Find the scale of the sides.
40/5=8 (the longer side is 8 times bigger than the shorter one)
3*8= 24
2x+10=24
Subtract 10 on both sides.
2x=14
Divide by two on both sides.
x=7
I hope this helps!

Answer:
x=35.35
Step-by-step explanation:
If you multiply 
by 10.1 that will cancel out the 10.1s, then since you multiplies one side of the equation by something you have to multiply the other too. So 3.5*10.1 = 35.35. Then since the 10.1s canceled out this leaves us with x=35.35. Let me know if you need any more help.
