[Question]The running time of Beast of War: Armoured Command is 10 minutes longer than that of Alpha Epsilon, which is 30 minutes shorter than that of Millennium. If Millennium runs for 2 hours, what is the running time of Beast of War: Armoured Command in minutes?
[Answer]One hour contains 60 minutes so 2 hours contain 60 * 2 = 120 minutes. Alpha Epsilon's running time is 30 minutes less than that of Millennium (which runs for 120 minutes) hence 120 - 30 = 90 minutes. Beast of War: Armoured Command runs for 10 minutes more than Alpha Epsilon hence 90 + 10 = 100 minutes. The answer is 100.

Question: Elizabeth wants to buy the steak knives from a bridal registry as a wedding gift. The couple registered for 2 steak knife sets and each set contains 4 steak knives. If Elizabeth buys both sets and they cost $80.00 per set, how much does each single steak knife cost?
Answer: Each steak knife set has 4 steak knives and Elizabeth bought 2 sets so there are 4 * 2 = 8 steak knives in total. Each steak knife set costs $80.00 and she bought 2 sets so she spent $80 * 2 = $160.00. Both sets cost $160.00 and there are 8 knives in total so each knife costs 160 / 8 = $20.00 each. The answer is 20.

Question: Sophia ate 1/6 of her pie and she put the rest on the fridge. If the pie left in the fridge weighs 1200 grams, how many grams did Sophia eat?
Answer:
If Sophia ate 1 / 6 of the pie, then 6 / 6 - 1 / 6 = 5 / 6 is left in the fridge. Let x be the pie's original weight. The current weight of the pie can be described by 5x / 6 = 1200 grams. So, 5x = 7200. And, the original weight is x = 1440 grams. So, Sophia ate 1440 grams original - 1200 grams after = 240 grams of pie. The answer is 240.
