Jolene invests her savings in two bank accounts, one paying 4 percent and the other paying 10 percent simple interest per year.

Nostrana [21]

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 $x$ . Lower yielding bank account will have $2x$ .

$Interest\text{ }per\text{ }year=Principal\times Interest\text{ }rate$

Interest from lower yielding bank = $\dfrac{4}{100} \times 2x=\dfrac{8x}{100}$

Interest from higher yielding bank = $\dfrac{10}{100} \times x=\dfrac{10x}{100}$

Total Interest per year = $ 3996 = $\dfrac{8x}{100} +\dfrac{10x}{100}=\dfrac{18x}{100}$

$x=22200 \$$

∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.
