Final answer:
To calculate the percentage of kilocalories from protein, you need to know the amount of kilocalories from protein and the total intake of kilocalories. The percentage of kilocalories from protein is between 10% and 15%.
Step-by-step explanation:
To calculate the percentage of kilocalories from protein, you need to know the amount of kilocalories from protein and the total intake of kilocalories. In the given information, it states that 10-15% of total calories should be obtained from protein. Let's assume a total intake of 100 kilocalories. To find the kilocalories from protein, multiply the total intake by the percentage of calories from protein, 10% to 15%:
100 kilocalories x 10% = 10 kilocalories
100 kilocalories x 15% = 15 kilocalories
Therefore, the percentage of kilocalories from protein is between 10% and 15%.
