You have asked to round the number to the nearest cent, but you have not said what the units are which that number represents. If it is 386.75 cents, then if we round it to the nearest cent, we get 387 cents. If, however, it is $386.75 then you can't round it to the nearest cent, you could only round it to the nearest dollar (in which case the answer would be $387).
