If Alice purchased 3600 acorns for nine times the price Bob paid, and Bob paid $6000 for his acorns, how much money did Alice pay for each acorn?
Thoughts? Step-by-step reasoning:
Nine times the price Bob paid for his acorns is 9 * $6000 = $54000. If Alice purchased 3600 acorns for nine times the price Bob paid, she paid $54000 / 3600 = $15 for each acorn.
Thus, the answer is 15.
