Hi there :)

The formula is
A=p (1+r/k)^kt
A future value?
P present value 2860
R interest rate 0.09
K compounded monthly 12
T time 3 years

A=2,860×(1+0.09÷12)^(12×3)
A=3,742.73

Hope it helps

Answer:

Option a - $3742.73

Explanation:

Given : John deposited $2860 in a bank that pays 9% interest, compounded monthly.

To find : The amount he will have at the end of 3 years ?

Solution :

Using compound interest formula,


A=P(1+r)^t

Where, A is the amount

P is the principle P=2860

r is the rate r=9%=0.09

t is the time t= 3 years

Compounded monthly,


r=(r)/(12)=(0.09)/(12)=0.0075


t=t* 12=3* 12=36

Substitute the value,


A=P(1+r)^t


A=(2860)(1+0.0075)^36


A=2860* 1.3086


A=3742.725

Therefore, Option a is correct.

The amount he will have at the end of 3 years is $3742.73
