Question

Lily likes to collect records. Last year she had 15 records in her collection. Now she has 24 records. What is the percent increase of her collection?

Answer 1

To find the percent increase of Lily's record collection, subtract the initial number from the final number, divide by the initial number, and multiply by 100.

Step-by-step explanation:

To calculate the percent increase of Lily's record collection, we need to find the difference between the initial and final number of records, and then divide that difference by the initial number of records. Finally, we multiply the result by 100 to express it as a percentage.

Initial number of records = 15

Final number of records = 24

Difference = 24 - 15 = 9

Percent increase = (9 / 15) * 100 = 60%
