Answer:
<h2>$ 22200 in higher yielding bank and $ 44400 in lower yielding bank</h2>
Step-by-step explanation:
Jolene invests in two bank accounts. The first account gives a 4% interest per year and the second bank gives a 10% interest rate per year.
She puts twice as much in the lower yielding bank account. Let us denote the amount put in high yielding bank account by
. Lower yielding bank account will have
.
![Interest\text{ }per\text{ }year=Principal\times Interest\text{ }rate](https://tex.z-dn.net/?f=Interest%5Ctext%7B%20%7Dper%5Ctext%7B%20%7Dyear%3DPrincipal%5Ctimes%20Interest%5Ctext%7B%20%7Drate)
Interest from lower yielding bank = ![\dfrac{4}{100} \times 2x=\dfrac{8x}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7B4%7D%7B100%7D%20%5Ctimes%202x%3D%5Cdfrac%7B8x%7D%7B100%7D)
Interest from higher yielding bank = ![\dfrac{10}{100} \times x=\dfrac{10x}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7B10%7D%7B100%7D%20%5Ctimes%20x%3D%5Cdfrac%7B10x%7D%7B100%7D)
Total Interest per year = $ 3996 = ![\dfrac{8x}{100} +\dfrac{10x}{100}=\dfrac{18x}{100}](https://tex.z-dn.net/?f=%5Cdfrac%7B8x%7D%7B100%7D%20%2B%5Cdfrac%7B10x%7D%7B100%7D%3D%5Cdfrac%7B18x%7D%7B100%7D)
![x=22200 \$](https://tex.z-dn.net/?f=x%3D22200%20%5C%24)
∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.

Determine the difference between the shortest and the longest
This question implies that we calculate the range.
![Range = Longest - Shortest](https://tex.z-dn.net/?f=Range%20%3D%20Longest%20-%20Shortest)
From the table, we have:
![Longest = 8.7m](https://tex.z-dn.net/?f=Longest%20%3D%208.7m)
![Shortest = 5.531m](https://tex.z-dn.net/?f=Shortest%20%3D%205.531m)
So, we have:
![Range = 8.7m- 5.531m](https://tex.z-dn.net/?f=Range%20%3D%208.7m-%205.531m)
![Range = 3.169m](https://tex.z-dn.net/?f=Range%20%3D%203.169m)
