Answer:
Ans. The value of investment after 2 years is $3,155.51
Explanation:
Hi, first we need toconvert that 9.80 percent, compounded quarterly into an effective quarterly rate, that is just by dividing by 4, since there are 4 quarters in a year, that is:
r(effective quarterly)= 9.8%/4 =2.45%
Now, since the rate is effective quarterly, the periods (time of the invesmet) has to be in quarters, so we multiply 2 years by 4 and we get 8 quarters.
With all the above information, we can go ahead and use the following formula in order to find the future value of this investment.

It should all look like this.

So, the future value of this investment is $3,155.51
Best of luck.
