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: 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%. The answer is 30.

A: Shyne can grow 14 x 4 = 56 eggplants. She can grow 10 x 6 = 60 sunflowers. So, she can grow a total of 56 + 60 = 116 plants in her backyard. The answer is 116.
Question: The total age of the people in Kaydence's family is 200. If Kaydence's father is 60 years old, Kaydence's mother 2 years younger than Kaydence's father, Kaydence's brother 1/2 the age of Kaydence's father, and Kaydence's sister 40 years old, how old is Kaydence?
Answer: If Kaydence's father is 60 years old, her mother is 60 - 2 = 58 years old. The total age of the mother and father is 60 + 58 = 118 years. Kaydence's brother is half the father's age, which is 1 / 2 * 60 = 30 years. The total age of Kaydence's father, mother, and brother is 30 + 118 = 148 years. If you add Kaydence's sister's age to the total age of the father, mother, and brother, you get 148 + 40 = 188 years. If everyone's age in the family is 200, then Kaydence's age is 200 - 188 = 12 years old. The answer is 12.
[Question]Zach is saving his money to buy a brand new bike that costs $100. His weekly allowance is $5. His parent will pay him an extra $10 to mow the lawn. His neighbor will pay him $7 per hour to babysit their son. He has already saved up $65. He'll receive his allowance on Friday and he's planning on babysitting for 2 hours this Saturday after he mows the lawn. How much more money does Zach need to earn before he can buy the bike?
[Answer]If he babysits for 2 hours at $7 per hour, he will earn 2 * 7 = $14. This week he will earn $5 allowance, $10 mowing the lawn and $14 from babysitting for a total of 5 + 10 + 14 = $29. If we add the $29 he will earn to his $65 savings, he will have a total of 29 + 65 = $94. The bike costs $100 and he will have $94 leaving $100 - $94 = $6 more that he will need to earn. The answer is 6.

From his second job, Mike receives $9 / hour * 12 hours = $108. He therefore earned $160 – $108 = $52 from his first job. The answer is 52.
