A company produces two joint products (called 101 and 202) in a single operation that uses one raw material called Casko. Four hundred gallons of Casko were purchased at a cost of $800 and were used to produce 150 gallons of Product 101, selling for $5 per gallon, and 75 gallons of Product 202, selling for $15 per gallon. How much of the $800 cost should be allocated to each product, assuming that the company allocates cost based on sales revenue?
