The mean cost of domestic airfares in the united states rose to an all-time high of $385 per ticket (bureau of transportation statistics website, november 2, 2012). airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. assume domestic airfares are normally distributed with a standard deviation of $110.

a. what is the probability that a domestic airfare is $550 or more (to 4 decimals)?
b. what is the probability than a domestic airfare is $250 or less (to 4 decimals)?
c. what if the probability that a domestic airfare is between $300 and $500 (to 4 decimals)?
d. what is the cost for the 3% highest domestic airfares?

The monthly demand equation for an electric utility company is estimated to be p equals 60 minus left parenthesis 10 superscript negative 5 baseline right parenthesis x, where p is measured in dollars and x is measured in thousands of killowatt-hours. the utility has fixed costs of $3 comma 000 comma 000 per month and variable costs of $32 per 1000 kilowatt-hours of electricity generated, so the cost function is upper c left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 32 x. (a) find the value of x and the corresponding price for 1000 kilowatt-hours that maximize the utility's profit. (b) suppose that the rising fuel costs increase the utility's variable costs from $32 to $38, so its new cost function is upper c 1 left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 38 x. should the utility pass all this increase of $6 per thousand kilowatt-hours on to the consumers?
