Since the number of units expected to be sold is uniformly distributed between 300 and 500, we know that the range of possible sales is also between 300 and 500. The only answer choice that reflects this range is C, 300 + 200x. 
If we use the RAND function in Excel to generate a set of 40 random numbers between 0 and 1, we can multiply each number by 200 and add 300 to get a set of random numbers between 300 and 500, which reflects our expected sales range. Therefore, the best choice is C.
