Answer:

10 2/3 years or 10 years and 8 months

Step-by-step explanation:

Assumed it is a simple interest with rate r.

4000(1 + 8r) = 5000
1 + 8r = 5000/4000
8r = 1/4
r = 1/32

<u>Find the time for the second amount:</u>

2100(1 + 1/32t) = 2800
1 + 1/32t = 2800/2100
1 + 1/32t = 1 1/3
1/32t = 1/3
t = 32/3
t = 10 2/3
