Hey there! Hello!

For this problem, take the interest equation into account: I = Prt. I is the interest, P is the principal amount that will be invested, r is the rate of interest per year (expressed in decimal form, where 90% is 0.9, for example), and t is the amount of time. Let’s solve the amount of money gained from interest after one year:

I = Prt
I=100*0.02*1
I=2

That means 2 dollars are earned after one year. If $102 is the total after one year, and interest is earned yearly, it surely can’t be $102 at the end of five years. So, let’s solve for five years this time:

I = Prt
I=100*0.02*5
I=10

So, at the end of five years, $110 will be earned. This is more than $102 dollars, meaning that your first answer choice is the correct one. 

Hope this helped you out! Feel free to ask me any additional questions you may have. 🙂
