Question: Five dozens of people are attending your family reunion. Your family was assigned to bring the cans of soda. Each box of soda contains 10 cans and costs $2 per box. It was assumed that each person can consume 2 cans of soda. If you are six in the family and agreed to pay equally for the cost, how much will each of your family members pay?
Answer with step-by-step thinking: Five dozens of people is equal to 5 x 12 = 60. 60 x 2 = 120 cans of soda are needed. So, this means 120 / 10 = 12 boxes of soda must be purchased. Thus, it will amount to $2 x 12 = $24. Therefore, each family member will pay $24 / 6 = $4.
So the answer is 4.

Question: Mary and her two friends agreed to evenly pay for the cost of 2 pounds of chicken. Mary's mother went to the grocery and bought the 2-pound chicken, 3 pounds of beef that cost $4 per pound, and a liter of oil that costs $1. If Mary's mother paid a total of $16 for the grocery, how much should Mary and her two friends pay each for the chicken?
Answer with step-by-step thinking:
Three pounds of beef cost $4 x 3 = $12. Mary's mother paid $12 + $1 = $13 for the beef and oil. Hence, the 2 - pound chicken cost $16 - $13 = $3. There are 1 (Mary) + 2 friends = 3 people who will split the $3 cost. Therefore, each of them will pay $3 / 3 = $1.
So the answer is 1.
