he Sinclair Company produces two products, turpentine and methanol (wood alcohol), by a joint process. Joint costs amount to $154,000 per batch of output. Each batch totals 6,000 litres: 25% methanol and 75% turpentine. Both products are processed further without gain or loss in volume. Separable processing costs are methanol, $1.00 per litre; irpentine, $0.45 per litre. Methanol sells for $6.80 per litre; turpentine sells for $4.70 per litre. equirement 1. How much joint costs per batch should be allocated to turpentine and to methanol, assuming that joint costs are allocated based on a physical measure (number of res at splitoff point) basis? alculate the amount of the joint costs per batch that will be allocated to turpentine and to methanol using the physical measure method. Assume that joint costs are allocated based n the number of litres at splitoff point. (Round the weightings to five decimal places.)
