Question

Monica deposited $26000 in an account that pays 4% interest compounded annually. How much money does she earn after 10 years?

Answer 1

Heres the formula for compound interest:
A=P(1+
`(r)/(n)`)^nt
A is the amount over 10 years
P is the initial deposit ($26,000)
r is the annual interest rate (4% or .04)
n is the number of times that interest is compounded annually (1)
t is the number of years the money is invested (10 yrs)
A=26000(1+
`(.04)/(1)`)^(1)(10)
A=26000(1.04)^10
A=26000(1.48024428492)
A=$38,486.3514079
(Simplified she would have $38,486.35)
