There are 25 candies in one bag. 2/5 of those 25 candies are caramels. 2/5 of 25 is 10 (because 1/5 of 25 is five, and 5 times 2 is 10). There are 10 caramels in each bag. Your answer is the option with 10 candies in each box model. One box represents one bag of candy (each box has 25 squares, meaning each box holds 25 candies).
