If $5700 is invested in a savings account which interest is compounded annually and if the 5700% turns into $6100 in 12 years, what is the interest rate of the savings account? ?

r=0.57%

Step-by-step explanation:

if $5700 is invested in a savings account which interest is compounded annually

$5700 turns into $6100 in 12 years

Compound interest formula is

P is the principal

r is the rate of interest

t is the time period

A is the amount in account after t years

P= 5700, A= 6100, t=12

divide by 5700 on both sides

take 12th root on both sides

now subtract 1 on both sides

r=0.00567

to get interest rate in percentage we multiply by 100

r=0.00567 * 100= 0.57%
