In a certain city, electricity costs $0.20 per kw·h. what is the annual cost for electricity to power a lamp-post for 8.00 hours

UNO [17]

Part a)

per day electricity power consumed when 100 W bulb is used for 8 hours

$P = 8 * 100 = 800 Wh$

for one year consumption

$E = 365 * 800 = 292 kWH$

now the cost will be given

$cost = 0.20 * 292 = $ 58.4$

now when other energy efficient light is used

$P = 8 * 25 = 200 Wh$

for one year consumption

$E = 365 * 200 = 73 kWH$

now the cost will be given

$cost = 0.20 * 73 = $ 14.6$
