Instructions: Read the scenarios below to answer the computational questions.

A traditional incandescent light bulb uses 60 watts of power and is turned on for 5 hours each day. An LED bulb with the same brightness uses only 10 watts.

Q1. Calculate the total energy used (in watt-hours) by the incandescent bulb in one day.

Q2. Calculate the total energy used (in watt-hours) by the LED bulb in one day.

Q3. How many watt-hours of energy are saved each day by using the LED bulb instead of the incandescent bulb?

Q4. If electricity costs $0.17 per kilowatt-hour (kWh), how much money would you save in one month (30 days) by switching from an incandescent to an LED bulb?

Q5. If the average home in the U.S. has 40 light bulbs, how much money would you save in an entire year by switching from incandescent to LED bulbs?
