At the time of her grandson's birth, a grandmother deposits $ 5000 in an account that pays 2 % compounded monthly. What will be the value of the account at the child's twenty-first birthday, assuming that no other deposits or withdrawals are made during this period?

The value of account will be $7607.15 at the child's 21st birthday.

Step-by-step explanation:

The formula of compound interest:

A= Amount after t years

P= Initial amount.

r = rate of interest

n= Number of interest pay in a year.

Given that, a grandmother deposit $5000 in an account that pay 2% compounded monthly at the time of her grandson's birth,.

Here P= $5000, r= 2%=0.02, n=12 and t= 21 years.

      ≈$7607.15

The value of account will be $7607.15 at the child's 21st birthday.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
