Question: Sara makes cakes during the five weekdays to sell on weekends. She makes 4 cakes a day and sells her cakes for $8. In 4 weeks she managed to sell all the cakes. How much money did she collect during that time?
Answer: Step-by-step reasoning process: During the week she makes 5 days / week * 4 cakes / day = 20 cakes. After selling them over the weekend she earns 20 cakes * $8 / cake = $160. In 4 weeks she raised $160 / week * 4 weeks = $640.
So the answer is 640.

Question: The chances of making the junior high basketball team start at 10% if you're 66 inches and increase 10% for every additional inch of height. Devin starts out as 65 inches tall, then grows 3 inches. What are his chances of making the basketball team?
Answer: Step-by-step reasoning process: First find Devin's new height by adding his growth to the original height: 65 inches + 3 inches = 68 inches. Then subtract 66 inches from Devin's height to find how many extra inches of height he has: 68 inches - 66 inches = 2 inches. Then multiply the number of extra inches by the percentage increase per inch to find the total percentage increase in his chances: 2 inches * 10% / inch = 20%. Then add the percentage increase to the base percentage to find Devin's overall chance of making the basketball team: 10% + 20% = 30%.
So the answer is 30.

Question: A couple opened a savings account. The husband gives $335 every week while the wife gives $225 every week. After 6 months of saving (assume 4 weeks in each month), they decided to divide half of the couple's savings into their four children's savings accounts. How much does each child receive?
Answer: Step-by-step reasoning process: The husband saves $335 x 4 = $1340 a month. The wife saves $225 x4 = $900 a month. Together, they save $1340 + $900 = $2240 in a month. In 6 months, their total savings is $2240 x 6 = $13440. Half of the couple's savings is 13440 / 2 = $6720. Therefore, each child will receive 6720 / 4 = $1680.
So the answer is 1680.

Question: At a convention, 16 of 36 delegates arrived with pre-printed name badges. Half of the remaining delegates made their own, hand-written name badges. How many delegates were not wearing name badges?
Answer:
Step-by-step reasoning process: There were 36 - 16 = 20 without pre - printed name badges. Then 20 / 2 = 10 made hand - written badges. There were 20 - 10 = 10 with no name badge.
So the answer is 10.
