ivied the total number of tennis balls buy the number of cans to see how many tennis balls are in 1 can
9 divided by 3 = 3
there are 3 tennis balls per can
fraction would be 3/1 ( meaning 3 balls to 1 can)
Answer:
$1,229.75
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
![A=P(1+\frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 3.25% into a decimal:
3.25% ->
-> 0.0325
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
![A=12,025(1+\frac{0.0325}{12})^{12(3)}](https://tex.z-dn.net/?f=A%3D12%2C025%281%2B%5Cfrac%7B0.0325%7D%7B12%7D%29%5E%7B12%283%29%7D)
![A=13,254.75](https://tex.z-dn.net/?f=A%3D13%2C254.75)
Lastly, subtract A from P to get the interest earned:
![13,254.75 - 12,025 = 1,229.75](https://tex.z-dn.net/?f=13%2C254.75%20-%2012%2C025%20%3D%201%2C229.75)
