Answer:
The money you will have is $98020.
Explanation:
It is given that grandparents deposit $2,000 each year on birthday and the account pays 7% interest compounded annually also the time is 21 years.
we will use the compound interest formula 
.
For the first birthday the amount after 21 yr will be:
Similarly for the second birthday amount after 20yr will be:
likewise, the last compound will be:
The total value of such compounding would be
:
![\text {Total amount}=2000[(1+\frac{7}{100})^{21}+(1+\frac{7}{100})^{20}...(1+\frac{7}{100})^{1}]](https://tex.z-dn.net/?f=%5Ctext%20%7BTotal%20amount%7D%3D2000%5B%281%2B%5Cfrac%7B7%7D%7B100%7D%29%5E%7B21%7D%2B%281%2B%5Cfrac%7B7%7D%7B100%7D%29%5E%7B20%7D...%281%2B%5Cfrac%7B7%7D%7B100%7D%29%5E%7B1%7D%5D)
The total amount just after your grandparents make their deposit is:
≈($96020+2000)
≈$98020
Hence, the money you will have is $98020.
