I need help with these three questions

SHOW ME NOW are made through a joint production process that ultimately produces 30 12-gauge shotguns and additional production process of the 20-gauge shotgun costs $25 per gun, after which it is sold for BE 19-4 Joint cost allocation-physical units method Blake's Blacksmith Co. produces two types of shotguns, a 12-gauge and 20-gauge. The shotguns photgun goes through an additional crafting process before it is sold. The additional production process of the 12-gauge shotgun costs $30 per gun, after which it is sold for $180 per gun. The $350 per gun. Determine the amount of joint production costs allocated to each type of shotgun using the physical units method. BE 19-5 Joint cost allocation-weighted average method obj. 5 Gary's Grooves Co, produces two types of carving knives, one with a handle made of a polymer that looks like walnut wood and another with a handle made with a polymer that looks like red oak. The knives are made through a joint production molding process that produces 330 knife blades for red oak handle knives and 220 knife blades for walnut handle knives at the split-off point. The polymer for the red oak handle knife blades requires twice as much cooling time as the polymer for the walnut handle knife blades, although all knives are removed from the joint mold- ing process at the same time (ie, once the cooling for the red oak handle knives is complete). The joint production process costs a total of $6,500. Assuming the company allocates joint costs using the weighted average method based on the required cooling time of the two joint products, determine the amount of joint production costs allocated to each type of knife using the weighted average method SHOW ME HOW SHOW ME HOW BE 19-6 Joint cost allocation-market value at split-off method Obj. 5 Man O'Fort Inc. produces two different styles of door handles, standard and curved. The door han- dles 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
