Based on the amounts that Jack invested into the different investment vehicles, the amount Jack earns a year would be $1,132.87.
How much does Jack earn from the high-yield savings account?
The amount invested is:
= 2 / 3 x 15,000
= $10,000
Amount after a year:
= Amount x e ^ (rate x time)
= 10,000 x e ⁰.⁰⁸ ˣ ¹
= $10,832.87
How much does Jack make from the regular savings account?
Amount invested:
= 1/3 x 15,000
= $5,000
Amount after a year:
= 5,000 x (1 + 6%)
= $5,300
How much did Jack earn in a year:
= (10,832.87 + 5,300) - 15,000
= $1,132.87
