Question

Lily likes to collect records. Last year she had 12 records in her collection. Now she has 15 records. What is the percent increase of her collection

Answer 1

To find the percent increase in Lily's record collection, subtract the original number of records from the current number of records, then divide the difference by the original number of records and multiply by 100%.

Step-by-step explanation:

To find the percent increase in Lily's record collection, we need to calculate the difference between the number of records she had last year and the number of records she has now, and then express that difference as a percentage of her original collection.

The difference between the two numbers is 15 - 12 = 3 records.

To find the percent increase, divide the difference (3) by the original number of records (12) and multiply by 100:

3/12 * 100 = 0.25 * 100 = 25%
