The demand curve for gasoline slopes downward and the supply curve for gasoline slopes upward. the production of the 1,000th gallon of gasoline entails the following:

• a private cost of $3.10;
• a social cost of $3.55;
• a value to consumers of $3.70.

let q represent the number of gallons of gasoline and let p represent the price of a gallon of gasoline. which of the following statements is correct?

a. one point on the demand curve is (q = 1,000, p = $3.55).
b. one point on the social-cost curve is (q = 1,000, p = $0.45).
c. one point on the supply curve is (q = 1,000, p = $3.10).
d. the socially optimal quantity of gasoline is less than 1,000 gallons

Auniversity spent $1.8 million to install solar panels atop a parking garage. these panels will have a capacity of 400 kilowatts (kw) and have a life expectancy of 20 years. suppose that the discount rate is 20%, that electricity can be purchased at $0.10 per kilowatt-hour (kwh), and that the marginal cost of electricity production using the solar panels is zero. hint: it may be easier to think of the present value of operating the solar panels for 1 hour per year first. approximately how many hours per year will the solar panels need to operate to enable this project to break even? a. a.3,696.48 b.14,785.92 c.9,241.20 if the solar panels can operate only for 8,317 hours a year at maximum, the project (would/would not)break even?

When a company produces and sells x thousand units per week, its total weekly profit is p thousand dollars, where upper p equals startfraction 800 x over 100 plus x squared endfraction . the production level at t weeks from the present is x equals 4 plus 2 t. find the marginal profit, startfraction dp over dx endfraction and the time rate of change of profit, startfraction dp over dt endfraction . how fast (with respect of time) are profits changing when tequals8?

Garcia industries has sales of $200,000 and accounts receivable of $18,500, and it gives its customers 25 days to pay. the industry average dso is 27 days, based on a 365-day year. if the company changes its credit and collection policy sufficiently to cause its dso to fall to the industry average, and if it earns 8.0% on any cash freed-up by this change, how would that affect its net income, assuming other things are held constant? a. $241.45b. $254.16c. $267.54d. $281.62e. $296.44
