7-14 the electrocomp corporation manufactures two electrical products: air conditioners and large fans. the assembly process for each is similar in that both require a certain amount of wiring and drilling. each air conditioner takes 3 hours of wiring and 2 hours of drilling. each fan must go through 2 hours of wiring and 1 hour of drilling. during the next production period, 240 hours of wiring time are available, and up to 140 hours of drilling time may be used. each air conditioner sold yields a profit of $25. each fan assembled may be sold for a $15 profit. formulate and solve this lp production mix situation to find the best combination of air conditioners and fans that yields the highest profit. use the corner point graphical approach.

As a result of a labeling mistake at the chemical factory, a farmer accidentally sprays weedkiller rather than fertilizer on half her land. as a result, she loses half of her productive farmland. if the property of diminishing returns applies to all factors of production, she should expect to seea. a decrease in the marginal productivity of her remaining land and an increase in the marginal productivity of her labor. b. an increase in the marginal productivity of her remaining land and an increase in the marginal productivity of her labor. c. an increase in the marginal productivity of her remaining land and a decrease in the marginal productivity of her labor. d. a decrease in the marginal productivity of her remaining land and a decrease in the marginal productivity of her labor.
