Using compound interest, it is found that he must invest his money at a rate of 8.78% a year.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:

In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
In this problem, the parameters are as follows:
t = 3, A(t) = 60000, P = 46150.3, n = 12.
Hence:



![\sqrt[36]{\left(1 + \frac{r}{12}\right)^{36}} = \sqrt[36]{1.3}](https://tex.z-dn.net/?f=%5Csqrt%5B36%5D%7B%5Cleft%281%20%2B%20%5Cfrac%7Br%7D%7B12%7D%5Cright%29%5E%7B36%7D%7D%20%3D%20%5Csqrt%5B36%5D%7B1.3%7D)



r = 12 x 0.00731451758
r = 0.0878.

Answer: GCF = 14
Step-by-step explanation:
The factors of all numbers:
14 - 2, 7, 14
28 - 2, 4, 7, 14, 28
42 - 2, 7, 14
As you can see, 14 is our GCF.

Answer:
Red: 1/2
White: 1/6
Blue: 1/3
Step-by-step explanation:
You take and find the total number of marbles, which is 18. You then take the number of each different color and make that number your numerator, and 18 your denominator and reduce.
Red: 9/18 reduces to 1/2
White: 3/18 reduces to 1/6
Blue: 6/18 reduces to 1/3
