Question

Suppose that you borrow

​$3000.00

from a friend and promise to pay back

​$4755.00

in

3

years. What simple interest rate will you​ pay?

Expert Solution
Step 1

It is given that the principal is 3000, balance is 4755 and time is 3 years.

The formula to evaluate the simple interest is I=P×r×t, where P is the principal, I is the interest amount, t is the time and r is the rate of interest.

The balance amount is given by A=P+I.

Therefore, A=P+P×r×t
