Mary consumes approximately 1800 kcalories per day. If she wants to consume 15% of her kcalories from protein, approximately how many grams of protein would she need each day?​

Respuesta :

Answer:

67.5 grams of protein per day

Explanation:

The total calories consumed by Mary per day = 1800 kcalories

The calories she wants to consume = 15% of her calories = 0.15 × 1800

= 270 kcalories

now,

1 gram of protein contains 4 kcalories of energy

or

1 kcalories of energy = (1/4) of protein

thus,

270 kcalories of energy = (1/4) × 270 = 67.5 gram of proteins

Thus,

Mary would need 67.5 grams of protein per day
