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
