A 77-hp motor that has an efficiency of 90.14% is soon to be obsolete. It will be replaced by a high efficiency motor which is 96.1% efficient. The motor operates 4,368 hours a year. Taking the cost of electricity to be ₱8.67 per kWh, compute for the annual savings due to the installation of the high-efficiency motor instead of the standard motor. Round your answer into two decimal places only.
You have a Switch LED Lightbulb with the following information: It is equivalent to a 60 Watt incandescent lightbulb. It uses 12 Watts of electricity. It is estimated to last 25,000 hours. The purchase price of the lightbulb is $42.99. The package claims an estimated energy cost of $1.45 per year, but this estimate is not based on local electricity costs. Assume that local electricity costs $0.086 per kW-hr. Based on this information, we can now calculate the cost of ownership for this bulb. The cost of ownership is defined as the purchase price of the lightbulb plus the cost of the electricity required to run the lightbulb until failure. Note the equation below: Purchase price + Total electricity cost = Cost of ownership Calculate the cost of ownership for this lightbulb $42.99 $25.80 $85.98 $68.79
