Answer:
The % increase is 7.179 but see the remark I made below. What I have given and what it could be is a rounding error. Less than 2 dollars error is not much when you are calculating something for someone just to show them how to do it.
Step-by-step explanation:
242,555 * x/100 = 259,970 Multiply by 100
242,555 * x = 259970 * 100
242,555 * x = 25997000 Divide by 242555
x = 24997000/242444
x = 107.179
That's the total increase.
What you want is 7.179%
If you take 7.179% of 242,555 and add it onto 242555 you should get 259,970
7.1797/100 * 242555 = 17413.02
17413.02 + 242555 = 259968.02
Why isn't it exact. I'm out just about 2 whole dollars. The reason is that the % isn't exact. It's only out to 3 decimal places which apparently is not enough. You can go over my numbers if you want more exactness us use something that is rounded to 7.180 if you like.

Answer:
y=19
Step-by-step explanation:
3(y - 9) = 30
3y - 27 = 30
3y = 30 + 27
3y = 57
y = 19

The formula for compound interest is written as
, where <em>P </em>is the principal (initial amount), <em>r</em> is the rate of interest, <em>n</em> is the number of times it's compounded per year, and <em>t</em> is the time in years. With the values from this problem plugged in, it looks like:
Since you're trying to find when your money will double, put 8000 for <em>A </em>and solve for <em>t</em><em /> :
It will take approximately 14.21 years, or about 14 years, 2 months, and 16 days, for the money to double.
