Maria has a savings account that is earning simple interest. if she started with $200 in the account and has earned a total of $8 in interest in two years, what is the rate of the account? use the formula r = i/pt. ! i just don't know!

Hi there! to find the simple interest rate of the account, divide the interest earned in a year by the principal. with $8 earned in interest after 2 years, that $4 in 1 year. do 4/200 in order to get 0.02. multiply that number by 100 to get 2. maria's savings account has a simple interest rate of 2%.
