Question: Lara is a contestant on a fun game show where she needs to navigate an inflated bouncy house obstacle course. First she needs to carry a backpack full of treasure through the obstacle course and set it down on the other side, which she does in 7 minutes and 23 seconds. Second, she needs to crank open the door to the obstacle course so she can go back through, which takes her 73 seconds. After she gets through the door she traverses the obstacle course again and makes it out faster without the backpack, in 5 minutes and 58 seconds. How many seconds total does it take her to complete the obstacle course?
Answer with step-by-step thinking: It takes Lara 7 minutes and 23 seconds to make it through the obstacle course the first time. 7 minutes x 60 seconds per minute = 420 seconds + 23 seconds = 443 seconds to get through the first part of the obstacle course. The second stage of the obstacle course she completes in 73 seconds + 443 seconds = 516 seconds. It takes 5 minutes and 58 seconds for Lara to get through the obstacle course the second time. 5 minutes x 60 seconds per minute = 300 + 58 seconds = 358 seconds. Combined, it takes Lara 516 + 358 seconds = 874 seconds for Lara to run the whole obstacle course.
So the answer is 874.

Question: Piazzanos Pizzeria has a buy-1-get-1-free special on triple cheese pizzas, and a buy-2-get-1-free special on meat lovers pizzas. If the standard price for a pizza is $5, how much does it cost, in dollars, to purchase 10 triple cheese and 9 meat lovers pizzas using the special pricing?
Answer with step-by-step thinking: Using buy - 1 - get - 1 - free pricing, it costs 1 * $5 = $5 to buy 2 triple cheese pizzas. At $5 per 2 pizzas, it costs $5 / 2 = $2.5 per triple cheese pizza. Using buy - 2 - get - 1 - free pricing, it costs 2 * $5 = $10 to buy 3 meat lovers pizzas. At $10 per three pizzas, it cost $10 / 3 = $3 and $1 / 3 per meat lovers pizza. With the buy - 1 - get - 1 - free pricing, 10 triple cheese pizzas are 10 * $2.5 = $25. With the buy - 2 - get - 1 - free pricing, 9 meat lovers pizzas are 9 * ($3 + $1 / 3) = $30. In total, for 10 triple cheese and 9 meat lovers pizzas, it will cost $25 + $30 = $55.
So the answer is 55.

Question: Chad sandwiches 2 crackers with a scoop of peanut butter. He has 5 of these crackers a night before bed. A box of crackers has 4 sleeves with each sleeve holding 28 crackers. How many nights will 5 boxes of crackers last him?
Answer with step-by-step thinking:
Chad uses 2 crackers for each "sandwich" and has 5 sandwiches a night so he eats 2 * 5 = 10 crackers a night. The box has 4 sleeves of crackers and each sleeve has 28 crackers for a total of 4 * 28 = 112 crackers. 1 box has 112 crackers so 5 boxes will have 112 * 5 = 560 crackers. He eats 10 crackers a night and 5 boxes have 560 crackers so they will last him 560 / / 10 = 56 nights.
So the answer is 56.
