Answer 1

Answer:

Option b is right

Step-by-step explanation:

Given that a person borrows money from a friend and they decide to use a simple interest formula. where I is the interest in dollars, P is the principle (original money loaned) in dollars, R is the interest rate, and T is the time in years.

Here we have simple interest formula as

$PRT/100$

substitute P = 3000, R = 2% and T = 3

to get

Simple interest for 3000 $ at 2% for 3 years

= $\frac{3000(2)(3)}{100} =180$

Answer is 180 dollars

Option b is right
