At the end of 4 years, she will have $54933
Step-by-step explanation:
Given-
Time to buy a new laptop, n = 4years
Quarterly deposit, C = $100 X 4 = $400 per year
Pays 3% per year compounded quarterly
We have to find the future value of Annuity
![FV = C * [((1 + i)^n - 1)/(i) ]](https://img.qammunity.org/2021/formulas/computers-and-technology/high-school/htcriu29cnncdnb9p8ry31qxznzkwutgpn.png)
Where, C = cash flow
i = interest rate
n = number of deposits
![FV = 400 [ ((1 + 3/400)^4)/(3/400) ]\\\\FV = 400 [ (1.03)/(0.0075) ]\\\\FV = 400 * 137.33\\FV = 54933](https://img.qammunity.org/2021/formulas/computers-and-technology/high-school/b7n4ybx8ae4ixlddxtaz2vd86spf6eonft.png)
