Jenny and Mark are throwing bottle caps. Jenny's bottlecap flies 18 feet straight, then bounces off a street light and flies another 1/3 of the distance it already went. Mark's bottle cap flies 15 feet forward, then bounces off a window and flies twice as far as it already did. How much further did Mark's bottle cap go than Jenny's? Give the rationale and then the answer.
Let's think step by step. First find 1 / 3 of the distance Jenny's bottlecap went straight: 18 feet / 3 = 6 feet. Then add that to the distance it flew straight to find the total distance it traveled: 6 feet + 18 feet = 24 feet. Then find twice the distance Mark's bottlecap went straight: 15 feet * 2 = 30 feet. Then add that distance to the distance it flew straight to find the total distance it traveled: 30 feet + 15 feet = 45 feet. Then subtract the distance Jenny's bottlecap traveled from the distance Mark's traveled to find the difference: 45 feet - 24 feet = 21 feet.. The answer is: 21.

Patrick buys a season pass for each of his sons to visit the local amusement park as often as they want. The passes were $100.00 each. The oldest son went to the park 35 times over the summer and the youngest went 15 times. What was the cost per trip to the park? Give the rationale and then the answer.
Let's think step by step. Patrick bought 2 tickets at $100.00 each for a total of 2 * 100 = $200.00. The oldest son went 35 times and the youngest went 15 times for a total of 35 + 15 = 50 trips. The tickets cost $200.00 and together, the boys went to the park 50 times so each trip cost 200 / 50 = $4.00.. The answer is: 4.

The electricity price in Coco's town is $0.10 per kW. Coco's new oven has a consumption rate of 2.4 kWh (kilowatt-hours). How much will Coco pay for using his oven only if he used it for a total of 25 hours last month? Give the rationale and then the answer.
Let's think step by step. If Coco used his oven 25 hours last month and its energy consumption is 2.4 kW per hour, then we consumed a total of 25 * 2.4 = 60 kW on his oven last month. If the price of electricity is $0.10 per kW, then 60 kW would cost = $0.10 * 60 = $6.. The answer is: 6.
