$1006.85 would be saved per month if the 8 watts LED replaced the 100 watts bulbs.

An equation is an expression that shows the relationship between two or more variables and numbers.

Amount of energy for the 100 watt bulb = 8 * 100 watt * 8 hr * 30 days =192000 Wh = 192 kWh

Amount of energy for the 8 watt bulb = 8 * 8 watt * 8 hr * 30 days = 15360 Wh = 15.36 kWh

The cost saved in a month = $5.7 * (192 - 15.36) = $1006.85

$1006.85 would be saved per month if the 8 watts LED replaced the 100 watts bulbs.
