Stahl Inc. produces three separate products from a common process costing $100, 100. Each of the products can be sold at the split-off point or can be processed further and then sold for a higher price. Shown below are cost and selling price data for a recent period. Determine total net income if all products are sold at the split-off point. Determine total net income if all products are sold after further processing. Calculate incremental profit/(loss) and determine which products should be sold at the split-off point and which should be processed further. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).) Determine total net income using the results from previous part. Is the net income different from that determined m part (b)
