The label on a juice carton says there are 50 calories in a 4 ounce serving of juice. If Arthur drinks 12 ounces of juice, how many calories will he consume?
A. 200 calories
B. 150 calories
C. 58 calories
D. 48 calories
He will consume 150 calories. I found the unit rate by dividing 50 calories by 4 ounces to get 12.5 calories per 1 ounce. I multiplied 12.5 calories by 12 ounces to get 150 calories.
