Final answer:
Shelley gets 1166.67 calories from fat and carbohydrates.
Step-by-step explanation:
Shelley gets 1/4 of her calories from fat and 1/3 from carbohydrates. To find out how many total calories she gets from fat and carbohydrates,
we need to calculate the respective fractions of her daily calorie intake. If Shelley eats about 2000 calories per day, 1/4 of that would be 2000 * 1/4 = 500 calories from fat, and 1/3 of that would be 2000 * 1/3 = 666.67 calories from carbohydrates.
Therefore, Shelley gets a total of 500 + 666.67 = 1166.67 calories from fat and carbohydrates combined.
