Question

I'm trying to figure out a math problem about stocks but I don't know how to solve a part of it. Will medal and fan!

Answer 1

20% you invest in a stock plan and the remainder is in a savings account at 2.90% APR compounded annually. The stock plan increases 8% the first year, decreases in value by 4% the second year, and increases by 6% the third year.

I've solved the first part of it:

20% of $20,000 is $4,000
The APR is 2.90, so multiply 4,000 by 1.0290 to get the first years total of $4,116

But now I don't know how to solve so the plan increases 8%?
