The cost of electricity varies widely throughout the United States; $0.120/kWh is a typical value. At this unit price, compute the cost of the following.

1. Leaving a 40.0-W porch light on for two weeks while you are on vacation.

2. Drying a load of clothes in 40.0 min in a 4,600 W dryer. (Give your answer to at least one decimal place.)

3. Making a piece of dark toast in 3.00 min with a 950-W toaster. (Give your answer to at least three decimal places.)
