your principal amount is = 3800$. 
your interest for the compound interest is equal to 0.0675/6
and your compounding period is equal to 6. 
so now Fv=a(1+rt)^n 
therefore 
Fv=3800(1+(0.0675/6))^6
what ever this works out to be will be your answer. 
Fv variable just means "future value." 
The rest is self explanatory.
