How do I calculate the Median value when using a separate Quantity column?

For example, say there are two columns, Quantity and Value. There are two
rows intersecting those columns which represent 99 purchases at $1 each
(Quantity: 99, Value 1) and 1 purchase at $99 (Quantity: 1, Value: 99). The
actual Median of those 100 purchases would be right around $1, but if you use
the Median function on the Value column, you're going to get around $50
because it's just seeing two values, 1 and 99.

So, how do you get the MEDIAN function to weight 99 separate 1's and a
single 99?
