Question

Anderson has a collection of 60 DVDs. Of these DVDs, 25% are comedy, 45% are horror, and the rest are romance. How many DVDs in Anderson's collection are romance?

Answer 1

25% = 15
45% = 27
27 - 15 = 12

12 movies are romance

Answer 2

18 DVDs

Explanation:

Step #1: Find the percent that are romance

Subtract the other percentages from 100% to find the percent that are romance.

100-25-45=30

So, 30% are romance

Step #2: Use the percentage to find the number of romance DVDs

Take 30%, convert it to a decimal.

30% becomes 0.3

Multiply this value times the original number of DVDs

0.3x60=18
