Mark prepared a fried egg, two pieces of toast, and a glass of orange
juice for breakfast. The egg contained 85 calories, the toast contained
70 calories each, and the orange juice contained 90 calories. What
percentage of his U.S. RDA for calories did the meal provide if he
needs 2,600 calories per day?
a. 12.12%
b. 8.25%
c. 315%
d. 43%
First, we need to find the total number of calories in the meal:
85 (egg) + 70 (toast) + 70 (toast) + 90 (orange juice) = 315 calories
Next, we can calculate the percentage of Mark's daily caloric needs that this meal provides:
315 / 2600 * 100% ≈ 12.12%
Therefore, the answer is (a) 12.12%.
To find the percentage of the U.S. Recommended Daily Allowance (RDA) for calories that the meal provided, we need to calculate the total number of calories in the meal and then divide it by the daily requirement.
Given:
- Egg: 85 calories
- Toast: 70 calories each (2 pieces = 2 * 70 = 140 calories)
- Orange juice: 90 calories
Total calories in the meal = 85 + 140 + 90 = 315 calories
To find the percentage, we divide the total calories in the meal by the daily requirement and then multiply by 100:
Percentage = (Total calories / Daily requirement) * 100
Percentage = (315 / 2600) * 100 = 0.1212 * 100 = 12.12%
Therefore, the percentage of his U.S. RDA for calories that the meal provided is 12.12%.
So, the correct answer is option a. 12.12%.
To calculate the percentage of Mark's U.S. Recommended Daily Allowance (RDA) for calories that the meal provided, we need to follow these steps:
Step 1: Calculate the total number of calories in the meal.
- The fried egg contained 85 calories.
- Two pieces of toast contained 70 calories each, so the total calories from the toast is 2 * 70 = 140 calories.
- The glass of orange juice contained 90 calories.
- Adding up the calories from each item, we get 85 + 140 + 90 = 315 calories.
Step 2: Calculate the percentage of Mark's U.S. RDA for calories the meal provides.
- Mark needs 2,600 calories per day.
- To calculate the percentage, divide the total number of calories in the meal (315 calories) by Mark's daily requirement (2,600 calories) and multiply by 100.
- (315 / 2600) * 100 = 12.12%
Therefore, the meal provided 12.12% of Mark's U.S. RDA for calories.
The correct answer is option a. 12.12%.
