The formula for the simple interest, I, is I=prt where p is principal, r is the annual interest rate, and t is the time elapsed in years.

solve the formula for r.

use the equation you just found to determine the annual interest rate on an account that earned $125.00 in simple interest after 6 months with principal deposit of $5.000.00.
