Tom eats a pound of carrots and twice as much broccoli. If carrots have 51 calories per pound and broccoli has 1/3 that many calories, how many calories did he eat in total? Let's be accurate as possible.
User
He ate 2 * 1 = 2 pounds of broccoli. There are 51 / 3 = 17 calories in each pound of broccoli. So he ate 2 * 17 = 34 calories of broccoli. He ate 1 * 51 = 51 calories of carrots. So in total he ate 51 + 34 = 85 calories.
The answer: 85.
