[Question]A sixty bulb watt uses 60 watts of power each day. If Allyn has 40 such bulbs in his house and pays an electricity bill of twenty cents per power watt used, calculate Allyn's total monthly expenses on electricity in June.
[Answer]
If each bulb uses 60 watts each day, the 40 bulbs that Allyn has uses 60 * 40 = 2400 watts of power each day. In June, with 30 days, the bulbs will use 30 * 2400 = 72000 watts of power. If Allyn is charged an electricity bill of twenty cents per power watt used, in June she will pay 72000 * $0.20 = $14400. The answer is 14400.
