Answer:
$ 22200 in higher yielding bank and $ 44400 in lower yielding bank
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 [tex]x[/tex]. Lower yielding bank account will have [tex]2x[/tex].
[tex]Interest\text{ }per\text{ }year=Principal\times Interest\text{ }rate[/tex]
Interest from lower yielding bank = [tex]\dfrac{4}{100} \times 2x=\dfrac{8x}{100}[/tex]
Interest from higher yielding bank = [tex]\dfrac{10}{100} \times x=\dfrac{10x}{100}[/tex]
Total Interest per year = $ 3996 = [tex]\dfrac{8x}{100} +\dfrac{10x}{100}=\dfrac{18x}{100}[/tex]
[tex]x=22200 \$[/tex]
∴ Jolene invested $ 22200 in higher yielding bank and $ 44400 in lower yielding bank.
