german

Answer:

After 20 years the investment will be worth 11,000$

Step-by-step explanation:

in order to solve the problem you have to turn the percent into a decimal by moving the percent sign twice to the left. which will result in ".11"

then you multiply 5,000x.11 and it equals to 550 per year.

multiply 550x20 and you get 11,000

if I'm not correct please tell me the right answer! goodluck!
