craig likes to collect records. last year he had 10 records in his collection. now he has 15 records. what is the percent increase of his collection?

His collection increased in a 20%.

Step-by-step explanation:

If 100% represents 10 records, what percentage would be for 12 records?

x = 12 100% / 10 = 120%

So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

rounding to the nearest thousandth would be 452,000
