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? Give the rationale and then the answer.
Let's think step by step. 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.. The answer is: 1.

Tom got 40 oranges and 70 apples. If he sold 1/4 of the oranges and 1/2 of the apples. How many fruits were left in total? Give the rationale and then the answer.
Let's think step by step. There are 40 + 70 = 110 oranges and apples altogether . He sold 40 x .25 = 10 pieces of oranges. He sold 70 x .50 = 35 pieces of apples. So, Tom was left with 110 - 10 - 35 = 65 pieces.. The answer is: 65.

Let's think step by step. Let x be the number of apples Kylie picked. Kayla picked (1 / 4)x apples. 200 = x + (1 / 4)x. 200 = (5 / 4)x. 200(4 / 5) = 160 = x apples. Kayla picked (1 / 4)(160) = 40 apples.. The answer is: 40.
