A package states that there are 60 calories in 12 crackers and 75 calories in 15 crackers. Since the relationship is proportional, how many calories are there in 180 crackers?xy12601575

Find the calories per cracker: 60 ÷ 12 = 5 calories per cracker. The second amount confirms the same rate, since 75 ÷ 15 = 5. For 180 crackers, 180 × 5 = 900 calories, so the answer is 900 calories.
