If a $20,000 investment earns $1,600 over 2 years, what is the annual interest rate?

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%

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
