hi i'm doing some practice questions, can someone help me. I want to check my work against the right answer.

A process involves incorporating 2,000 units input of material costing $2,000 with labor costs of$2,000 and overheads of$1,000. The output of the process is two joint products: 600 units P1, 1,200 units P2; and 200 units of by-product.

The by-product will be able to be sold for $50 in total. Allocate the joint costs on a physical units basis.
