What was the question for this implicit rationale, and corresponding answer?
Anna bought 3 packs of chewing gum that were $1 each for a total of 3 * 1 = $3. Anna bought 5 chocolate bars that were $1 each for a total of 5 * 1 = $5. Anna bought 2 large candy canes that were $.50 each for a total of 2 * .50 = $1. The total amount spent was $3 + $5 + $1 = $9.00.
