1) Mike was trying to pick out lighting for his new home and was choosing between Incandescent and CFL light bulbs. Incandescent bulbs are $0.75 each and CFL's are $1.85 each. Incandescent bulbs last about 750 hours before needing to be replaced, while CFL's last about 10,000 hours. What is the difference in the cost per hour for each bulb? 2) Elliott was looking to save money and make his home more energy efficient. He heard about LED light bulbs, but wanted to calculate the actual cost per year before buying them. Elliott found that Incandescent bulbs cost $0.01 per hour in electricity, while LED's cost $0.0022 per hour. If the average user has their lights on for 4 hours per day, and has 70 light bulbs in their house, what is the cost to use incandescent bulbs for a year? What about LED bulbs for a year? What are the savings per year to switch to LED's? 3) Jamie was in the market for a new washer and dryer. The old ones still worked, but not efficiently. The new washer and dryer cost $1450 for both of them. The cost of the old washer and dryer to run was $1.05 per day. The new washer and dryer are energy efficient and cost $0.22 per day to run. How long will it take for Jamie to get her money back in savings
