Bodean is making a birthday gift for his sister, Brandine. He fills a jar with frogs and jawbreakers. For each frog he puts in the jar, he puts in three jawbreakers. When he has used up all his frogs, he covers them with an extra 6 jawbreakers. What is the rule for calculating the number of jawbreakers in the jar from the number of frogs? If he puts in 10 frogs, how many jawbreakers does he put in?
jawbreakers = 6 + (frogs x 3)
6 + (10 x 3) = 36
