Cafeteria Trading


During lunch, students like to trade their
food. The following exchange rates are
used in the cafeteria: 2 candy bars can be
traded for 3 pieces of pizza, and 1 piece of
pizza can be traded for 4 lollipops. Using
this exchange rate, how many lollipops
would you accept for 1 candy bar? Explain
your reasoning for this exchange.
