How much would it cost to watch a football game for 3.0 h on a 325 W television described in item 43 if electrical energy costs $0.08/kW •h?
To calculate the cost of watching a football game for 3.0 hours on a 325 W television, we need to first calculate the total energy consumed by the television.
Energy = power x time
Energy = 325 W x 3.0 h
Energy = 975 Wh or 0.975 kWh
Now, we can calculate the cost of this energy consumption based on the given electricity cost.
Cost = Energy x Cost per kWh
Cost = 0.975 kWh x $0.08/kWh
Cost = $0.078
Therefore, it would cost approximately $0.08 to watch a football game for 3.0 hours on a 325 W television, assuming an electricity cost of $0.08/kWh.
