Rounding question

Question

Suppose I have the following question:

Every week the sales of a band’s album drop by the same percentage relative to the previous week’s sales. In its first week an album sells 8,000 copies. In its seventh week an album sells 2,800 copies. Assuming this trend continues, calculate the total number of albums which will be sold. Round your answer to the nearest album.

I've done all the work and gotten a calculation of 49838.61...

HOWEVER, it says I need to round to the nearest album. Do I round up like I usually would or would I round down because you can't sell a fraction of an album and that doesn't equate to another CD being sold?

Answer 1

In my experience as a student, you should round up if the item cannot be divided. This is especially true in this case because your calculated answer contains a decimal of >0.5. This would lead you to round up anyway.
