Please show and explain how to work through these problems. I'm having a hard time understanding how to solve.

Joint Cost Allocation-Weighted Average Method another with a casing made with a polymer that looks like red oak. The casings are made through a joint production molding process that produces 500 red oak casings and 250 walnut casings at the split-off point. The polymer for the reaking time as the polymer for the walnut casings, although all casings are removed from the joint molding process at the same time (i.e., once the cooling for the red oak casings is complete). The joint production process costs a total of $7,200. determine the amount of joint production costs allocated to each type of casing using the weighted average method. Feedback Vheck My Work The weighted average method also uses a physical measure of the products at the split-off point, but then multiplies these measures by weight factors for each product. These weighted average units are then used to allocate the joint costs to the products. Joint Cost Allocation-Market Value at Split-off Method Gripturn Inc. produces two different styles of door handles, standard and curved. The door handles go through a joint production molding process costing $29,000 per batch and producing 2,000 standard door handles and 1,000 curved door handles at the split-off point. Both door handles undergo additional production processes after the split-off point, but could be sold at that point: the standard style for $4 per door handle and the curved style for $2 per door handle. Determine the amount of joint production costs allocated to each style of door handle using the market value at split-off method
