Answer:

Annual interest rate = 4%

Step-by-step explanation:

We are given;

Principal; P = $20000

Interest; I = $1600

Period; T = 2 years

Formula for simple interest is;

I = PRT

Making R, rate the subject of the formula gives;

R = I/PT

Plugging in the relevant values gives;

R = (1600)/(20000 × 2)

R = 0.04

In percentage form, R = 4%
