This should make it more clear! I tried to make it as clear as possible but please let me know if something is blurry or unclear!
7 is the square root or 49 because 7 times Itself would be 49. (7x7=49)
<span><u><em>9.24 is 24% of 38.5</em></u>
</span>100%=38.5
x%=9.24
100%/x%=38.5/9.24
(100/x)*x=(38.5/9.24)*x
100=4.16666666667*x
y (4.16666666667) to get x
100/4.16666666667=x
24=x
x=24
He will earn $126 in interest.
How did I solve this:
Find the decimal of 4%:
4% = 0.04
Multiply 0.04 times 525:
0.04 x 525 = 21
Multiply $21 times 6 years:
21 x 6 = 126
126 is your correct and finale answer.
Hope this helps! =)
