Marty owns a machine shop. in reviewing the shop's utility bills for the past 12 months, he found that the highest bill of $ 2 comma 600 occurred in august when the machines worked 1 comma 400 machine hours. the lowest utility bill of $ 2 comma 300 occurred in december when the machines worked 900 machine hours. read the requirements requirement 1. use the high-low method to calculate the variable cost per machine hour and the total fixed utility cost. first, calculate the variable cost per machine hour. select the formula labels, then enter the amounts and compute the variable cost per machine hour. (use the high-low method. round your answer to the nearest cent.) /

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?
