To determine for which vitamins Robert met at least 75% of his recommended daily allowance, let's analyze his intake for each vitamin.
1. Vitamin B12:
- Recommended daily allowance: 2.4 micrograms.
- Intake from salmon fillet: 5.87 micrograms.
- Intake from boiled green beans: 0.0 micrograms.
- Intake from strawberries: 0.0 micrograms.
- Total intake: [tex]\( 5.87 + 0.0 + 0.0 = 5.87 \)[/tex] micrograms.
- Percentage of daily allowance: [tex]\( \frac{5.87}{2.4} \times 100 \approx 244.58\% \)[/tex].
2. Vitamin C:
- Recommended daily allowance: 75 mg.
- Intake from salmon fillet: 0.0 mg.
- Intake from boiled green beans: 12.1 mg.
- Intake from strawberries: 49.0 mg.
- Total intake: [tex]\( 0.0 + 12.1 + 49.0 = 61.1 \)[/tex] mg.
- Percentage of daily allowance: [tex]\( \frac{61.1}{75} \times 100 \approx 81.47\% \)[/tex].
3. Vitamin E:
- Recommended daily allowance: 15 mg.
- Intake from salmon fillet: 0.60 mg.
- Intake from boiled green beans: 0.57 mg.
- Intake from strawberries: 0.42 mg.
- Total intake: [tex]\( 0.60 + 0.57 + 0.42 = 1.59 \)[/tex] mg.
- Percentage of daily allowance: [tex]\( \frac{1.59}{15} \times 100 \approx 10.6\% \)[/tex].
From the calculations:
- Vitamin B12 intake is approximately 244.58% of the recommended daily allowance, which is well above 75%.
- Vitamin C intake is approximately 81.47% of the recommended daily allowance, which is above 75%.
- Vitamin E intake is approximately 10.6% of the recommended daily allowance, which is below 75%.
Therefore, Robert met at least 75% of his recommended daily allowance for Vitamin B12 and Vitamin C only.
