If 22000 is invested at 12% interest compounded quarterly, find the interest earned in 12 years.

Interest earned in 12 years = 57178

Step-by-step explanation:

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

then

P=22000 , r=12% , n=12 and t=12 years

putting these value

        = 22000(2.5992729255593856)

        = 57178

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
