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?

900 calories

step-by-step explanation:
there are 60 calories in 12 crackers or 5 calories per crackers
60/12 = 5
there are 75 calories in 15 crackers or 5 calories per crackers
75/15 = 5
if there are 180 crackers
180 • 5
900 calories total
