In a household, a business is run for an average of 6 hours per day. The total power consumed by the computer and its printer is 230 watts. In addition, a 75-W light runs during the same 6 hours. If their utility charges 11.75 cents per kWhr, how much do the owners pay every 30 days?
What will be an ideal response?
Total energy consumed over every 30 day period = 30[(230+75)6] = 54.9 kWhr
Cost per 30 day period = $0.1175x54.9 = $6.451
