The monthly demand equation for an electric utility company is estimated to be p = 76 - (10-5)x, where p is measured in dollars and x is measured in thousands of killowatt-hours. The utility has fixed costs of $9,000,000 per month and variable costs of $46 per 1000 kilowatt-hours of electricity generated, so the cost function is C(x) = 9• 106 + 46x. (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 $46 to $56, so its new cost function is C, (x) = 9• 106 + 56x. Should the utility pass all this increase of $10 per thousand kilowatt-hours on to the consumers? (a) Find the value of x and the corresponding price for 1000 kilowatt-hours that maximize the utility's profit. x=0 (Type an integer or a decimal.) X =

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

The monthly demand equation for an electric utility company is estimated to be p = 76 – (10)x, where p is measured
in dollars and x is measured in thousands of killowatt-hours. The utility has fixed costs of $9,000,000 per month and
variable costs of $46 per 1000 kilowatt-hours of electricity generated, so the cost function is C(x) = 9• 106 + 46x.
(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 $46 to $56, so its new cost function is
C, (x) = 9• 106 + 56x. Should the utility pass all this increase of $10 per thousand kilowatt-hours on to the consumers?
(a) Find the value of x and the corresponding price for 1000 kilowatt-hours that maximize the utility's profit.
X =

According to the U.S. Census Bureau, in 2011, the median (middle of the range) annual income of a high school graduate with no further education was about $35,400 per year. If we assume that it takes 4 years to earn a bachelor's degree and 2 additional years to earn a master's degree, the median annual income increases by 12% for each year spent toward successful completion of a degree. This describes a function I = I(y), where I is the median income in 2011 for a person with y years of college education.
