Product M and S are joint products. The joint production cost of the products is $1500. That is, there are costs up to a certain point and we cannot divide the products before that point. M has a market value of $2000 at the split-off point. If M is further processed at an additional cost of $900, its market value is $3000. Product S has a market value of $3000 at the split-off point. If Product S is further processed at an additional cost of $1000, its market value is $4500. Using the relative sales value method (Using the sales price at slit off), calculate the joint product cost that would be allocated to M and S.
