Final answer:
The tree, initially 9 feet tall, grew 14% by December, making it 10.26 feet tall by the end of that period.
Step-by-step explanation:
The question asks how tall the tree was in December after it grew 14% from its original height in January. Since the tree was 9 feet tall in January, we use the growth rate to calculate the height in December. To find the increased height, we can calculate 14% of the original height and then add it to the original height.
To find 14% of 9 feet:
- Convert the percentage to a decimal: 14% = 0.14.
- Multiply the decimal by the original height: 0.14 × 9 feet = 1.26 feet.
- Add the increase to the original height: 9 feet + 1.26 feet = 10.26 feet.
Therefore, the tree was 10.26 feet tall in December after growing 14% from January.
