Question: The price of electricity went up by 25%. John's old computer used 800 watts and his new computer uses 50% more. If the old price of electricity was 12 cents per kilowatt-hour, how much does his computer cost, in dollars, to run for 50 hours?
Answer: His new computer uses 800 * .5 = 400 watts more than his old computer. So it users 800 + 400 = 1200 watts. That is 1200 / 1000 = 1.2 kw. Electricity cost 12 * .25 = 3 cents more than it used to. So it now cost 12 + 3 = 15 cents per kwh. He used 1.2 * 50 = 60 kwh. So he paid 15 * 60 = 900 cents per kwh. So he paid 900 / 100 = $9. The answer is 9.
[Question]The garbage truck passes through Daniel's neighborhood on Tuesdays, Thursdays, and Saturdays. In each garbage collection, an average of 200 kg is taken. Due to obstruction in the roads leading to Daniel's neighborhood, the garbage truck stops passing through for two weeks. During the first week, people in Daniel's neighborhood pile the extra garbage around the dumpster, during the second week they apply a policy of cutting their amount of garbage in half. How many kilograms of garbage have accumulated in Daniel's neighborhood during the 2 weeks?
[Answer]The garbage truck passes through Daniel's neighborhood for 3 days. In the first week, 200 * 3 = 600 kilograms of garbage are accumulated. In the second week, half the amount of garbage is accumulated, which is 600 / 2 = 300 kg of garbage. During the 2 weeks, 600 + 300 = 900 kg of garbage are accumulated. The answer is 900.

Question: Tricia ordered three dozen eggs. She will use 1/4 of them for making crepes, and 2/3 of the remaining for making cupcakes. How many eggs are left to make sunny-side-up eggs for breakfast?
Answer: Since a dozen is equal to 12, then 3 dozen eggs are equal to 12 x 3 = 36 eggs. Tricia will use 36 x 1 / 4 = 9 eggs for making crepes. So there are 36 - 9 = 27 eggs left. 27 x 2 / 3 = 18 eggs will be used for making cupcakes. Thus, there are only 27 - 18 = 9 eggs left to make sunny - side - up eggs for breakfast. The answer is 9.
