Final answer:
Sugar has 48 calories per tablespoon.
Step-by-step explanation:
To find the number of calories per tablespoon of sugar, we can set up a proportion using the given information:
3 tablespoons of sugar has 144 calories, so 1 tablespoon of sugar has x calories.
We can set up the proportion as:
3/1 = 144/x
Cross multiplying gives us:
3x = 1 * 144
Dividing both sides by 3 gives us:
x = 144/3
x = 48
Therefore, sugar has 48 calories per tablespoon.
