Parker county community college (pccc) is trying to determine whether to use no insulation or to use insulation that is either 1 inch thick or 2 inches thick on its steam pipes. the heat loss from the pipes without insulation is expected to cost $1.30 per year per foot of pipe. a 1-inch thick insulated covering will eliminate 89% of the loss and will cost $0.40 per foot. a 2-inch thick insulated covering will eliminate 92% of the lost and will cost $0.85 per foot. pccc physical plant services estimates that there are 150,000 feet of steam pipe on campus. the pccc accounting office requires a 10%/year return to justify capital expenditures. the insulation has a life expectancy of 10 years. what is the annual worth of each option? no insulation: $1-inch insulation: $2-inch insulation: $ carry all interim calculations to 5 decimal places and then round your final answer to the nearest dollar. the tolerance is ±20. show a negative amount preceded by a minus sign.

Consider how health insurance affects the quantity of health care services performed. suppose that the typical medical procedure has a cost of $160, yet a person with health insurance pays only $40 out of pocket. her insurance company pays the remaining $120. (the insurance company recoups the $120 through premiums, but the premium a person pays does not depend on how many procedures that person chooses to undergo.) consider the following demand curve in the market for medical care. use the black point (plus symbol) to indicate the quantity of procedures demanded if each procedure has a price of $160. then use the grey point (star symbol) to indicate the quantity of procedures demanded if each procedure has a price of $40. q d at p=$160 q d at p=$40 0 10 20 30 40 50 60 70 80 90 100 200 180 160 140 120 100 80 60 40 20 0 price of medical procedures quantity of medical procedures demand if the cost of each procedure to society is truly $160, the quantity that maximizes total surplus is procedures. economists often blame the health insurance system for excessive use of medical care. given your analysis, the use of care might be viewed as excessive because consumers get procedures whose value is than the cost of producing them.
