Come up with a question and reasoning that would justify [8] as the answer.
The question is: Edward had $17.80 to spend at the toy store. He bought 4 toy cars that cost $0.95 each and a race track that cost $6.00. How much money does Edward have left to buy more toys?
Reasoning: The cost of the toy cars is 4 $0.95 = $3.80. The total cost of the toys is $3.80 + $6.00 = $9.80. Edward has $17.80 $9.80 = $8.00 left.

Come up with a question and reasoning that would justify [1] as the answer.
The question is: 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?
Reasoning: 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.

Come up with a question and reasoning that would justify [40] as the answer.
The question is: The sum of the ages of two friends, Alma and Melina, is twice the total number of points Alma scored in a test. If Melina is three times as old as Alma, and she is 60, calculate Alma's score in the test?
Reasoning: If Melina is three times as old as Alma, and she is 60, Alma is 60 / 3 = 20 years old. The sum of their ages is 60 + 20 = 80 years. Since the sum of Alma and Melina's age is twice the total number of points Alma scored in a test, Alma's score in the test was 80 / 2 = 40 points.
