Answer:
Ashley had $48.11 before she bought the book.
Explanation:
If Ashley bought a book for $15.99 and now has $32.12, then before the purchase, she had:
Amount before purchase = Amount after purchase + Price of the book
Amount before purchase = $32.12 + $15.99
Simplifying:
Amount before purchase = $48.11
Therefore, Ashley had $48.11 before she bought the book.
