Lucía purchased a collector's edition book for $⁢150 However, a few pages were missing, reducing its value to $⁢127.50 What is the percent decrease in the value of the book?

The book’s value decreased by $150 − $127.50 = $22.50. Divide the decrease by the original value and multiply by 100: ($22.50 ÷ $150) × 100 = 15 percent, so the correct choice is 15 percent.
