Answer:
compound interest rate is 9.97%
Explanation:
given data
deposit amount = $24,000
rate = 11% per year
time = 3 year
to find out
compound interest rate
solution
simple interest = P ( 1+rt) ...............1
simple interest = 24000 ( 1+ 0.11 ×3 )
simple interest = $31920
so
compound interest rate is
amount = P ( [tex](1+r)^t[/tex] ) ................2
31920 = 24000 ( [tex](1+r)^3[/tex] )
1.33 = [tex](1+r)^3[/tex]
r = 0.09972 = 9.97 %
so compound interest rate is 9.97%
