Since x is a random number between 0 and 1, and the number of units expected to be sold is uniformly distributed between 300 and 500, we can use a linear function to determine the sales. The slope of this function is the change in sales per unit change in the expected number of units sold, which is (500-300)/(1-0) = 200. The y-intercept is the sales when the expected number of units sold is 0, which is 300. Therefore, the expression for sales is 300 + 200x, which is Choice C.
