13) The owner of Firewood To Go is considering buying a hydraulic wood splitter
which sells for $50,000. He figures it will cost an additional $100 per cord to purchase
and split wood with this machine, while he can sell each cord of split wood for $125. If,

day, and actual output is anticipated to be 35 cords per day, what would be its
utilization?

17) The logistics/operations manager of a mail order house purchases two products for
resale: king beds (K) and queen beds (Q). Each king bed costs $500 and requires 100
cubic feet of storage space, and each queen bed costs $300 and requires 90 cubic feet of
