While gaming, a Playstation 4 uses about 140 Watts of energy. A flat-screen TV uses about 150 Watts. If you are gaming for 4 hours a day 5 times a week for a year, how much will that cost you if you pay 5 cents/kWh? Your answer should have $/kWh as the unit. *

Step-by-step explanation:

The problem statement tells you the cost of energy is $0.05/kWh. If those are the units required for the answer, that is the answer.

The question, "how much will that cost you?" suggests the units of the answer should be dollars (not dollars per kWh). In that case, we need to know the number of kWh used during the year. The total annual cost will be ...

  (0.14 kW +0.15 kW)(4 h/day)(5 day/wk)(52 wk/yr)(1 yr)($0.05/kWh)

  = (0.29)(4)(5)(52)($.05) = $15.08

Your cost will be $15.08 for the electricity for a year.
