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? Think carefully first, then make a decision:

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.
