Answer:

7 11/23%

Explanation:

To find rate u use the method of finding simple interest

Simple interest= Principal× Rate × Time

SI=PRT/100

$4000=$18000×r×3yrs/100

Now u divide 100 by 18000

To do that u cancel out all the zeros

Now u remain with;-

$4000=$180×r×3yrs

$4000= $540×r

Now u divide;-

$4000/540=540×r/540

The answer is 7 11/23%
