An engineer is trying to formulate the minimum cost set of materials to use in an upcoming project. There are four groups of materials, and exactly one item from each group must be selected. The costs are given below: Group A Cost Group B Cost Group C Cost Group D Cost A1 10 B1 2 C1 8 D1 5 A2 12 B2 1 C2 9 D2 8 A3 16 C3 11 D3 9 C4 13
If B2 is selected, then A3 must be used. We can use at most one of A1, B1, C1, and D1, while we must have at least two of A3, C3, C4, and D3. Finally, D1 cannot be used unless A2 or C4 is used. Formulate and solve a 0-1 integer programming model that will determine the optimal solution.

Kandon enterprises, inc., has two operating divisions; one manufactures machinery and the other breeds and sells horses. both divisions are considered separate components as defined by generally accepted accounting principles. the horse division has been unprofitable, and on november 15, 2018, kandon adopted a formal plan to sell the division. the sale was completed on april 30, 2019. at december 31, 2018, the component was considered held for sale. on december 31, 2018, the company’s fiscal year-end, the book value of the assets of the horse division was $415,000. on that date, the fair value of the assets, less costs to sell, was $350,000. the before-tax loss from operations of the division for the year was $290,000. the company’s effective tax rate is 40%. the after-tax income from continuing operations for 2018 was $550,000. required: 1. prepare a partial income statement for 2018 beginning with income from continuing operations. ignore eps disclosures. 2. prepare a partial income statement for 2018 beginning with income from continuing operations. assuming that the estimated net fair value of the horse division’s assets was $700,000, instead of $350,000. ignore eps disclosures.
