[Question]The football coach makes his players run up and down the bleachers 40 times. Each time they run up and down 32 stairs one way. If each stair burns 2 calories, how many calories does each player burn during this exercise?
[Answer]First find the number of stairs the players climb up and down each time: 32 stairs * 2 = 64 stairs. Then multiply the number of stairs per run by the number of runs to find the total number of stairs the players climb: 64 stairs / run * 40 runs = 2560 stairs. Then multiply the number of stairs by the number of calories each stair burns: 2560 stairs * 2 calories / stair = 5120 calories. The answer is 5120.

Question: Samanta is planning a party for her friend Marta. She decided to raise some money among the guests she invited, to buy Marta a gift. Every participant gave Samanta $5 for this purpose and she herself put in $10. The gift cost was lower than expected, so there was $15 leftover. What was the price of the gift, if there were 12 guests invited?
Answer:
From all the guests Samanta got $5 / guest * 12 guests = $60. Including money Samanta put herself, she had $60 + $10 = $70. The cost of the gift was $70 - $15 = $55. The answer is 55.
