Anna also wants to travel after graduation but she isn’t working while in school so she won’t be able to put money aside regular

Molodets [167]

Answer:

She will have $2792 at the end of her four year investment

Step-by-step explanation:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Gift of $2500:

This means that $P = 2500$

She shopped around and found a 4 year GIC investment that earns 2.8% interest annually.

This means that $t = 4, r = 0.028, n = 1$ .

How much will Anna have at the end of her four year investment?

This is A(4). So

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(4) = 2500(1 + 0.028)^{4} = 2792$

She will have $2792 at the end of her four year investment
