- PECO currently charges 12.927 cents per kilowatt-hour for electricity. What is the cost ofelectricity to operate a 1475-watt space heater for 510 minutes each day for the months ofFebruary and March?We found that the estimated rate of increase in the cost when x = 60,000 is $438 per game system. We are asked to compare this estimate to the exact cost of producing the 60,001st game system. In order to find the exact cost of producing the 60,001st game system, we can find the exact cost of producing 60,000 game systems in an hour and the exact cost of producing 60,001 game systems in an hour and take the difference of the two numbers. Recall that the cost for the company to produce x game systems per hour is given by the cost function C(x) = 900,000 + 390x + 0.0004x2. So the cost for the company to produce 60,000 game systems in an hour is given by the following. C(x) = 900,000 + 390x + 0.0004x2 C(60,000) = 900,000 + 390(60,000) + 0.0004(60,000)2 = 25740000 The cost for the company to produce 60,001 game systems in an hour is given by the following. C(x) = 900,000 + 390x + 0.0004x2 C(60,001) = 900,000 + 390(60,001) +…Because the price of the new package is the same as the original package, the price of each piece (ie the unit price) in the new package has increased from the price of each piece (ie the unit price) in the original package.
