Moderate# Laptop Yearly

APES-LCE2K4

If a laptop uses $60\text{ W}$ of electricity per day and is plugged in for eight hours per day, it will use approximately $480\text{ Wh}$ of electricity per day.

$$\cfrac { 60\text{ W} }{ 1 \text{ day} } \times \cfrac { 8\text{ h} }{1\text{ day} } = 480\text{ Wh per day}$$

If electricity costs $ \$0.10 \text{ per kWh}$, how much will it cost to charge this laptop each year?
