Question

A dog weighs 64 pounds, he eats 3/4 cup of food twice a day. his food contains 429 kcal/cup and 6.5grams protein per 100 kcal of energy. What is the dogs daily energy and protein intake? express energy intake as kilocalroies and protein as grams.

Answer 1

the dogs daily energy intake is 643.5 kcal

and, the dogs daily protein intake is 41.8275 grams

Explanation:

Given:

Food taken per day = 2 ×
`\frac{\textup{3}}{\textup{4}}` cup = 1.5 cup

Amount of calories in a cup = 429 kcal/cup

Amount of protein = 6.5 grams per 100 kcal of energy

now,

The total amount of calories taken per day

= Number of cups of food × Amount of calories in a cup

= 1.5 × 429

= 643.5 kcal

also,

100 kcal of energy = 6.5 grams protein

thus,

1 kcal of energy = 0.065 grams protein

therefore,

643.5 kcal of energy = 0.065 × 643.5 grams protein

or

643.5 kcal of energy = 41.8275 grams of proteins

Hence,

the dogs daily energy intake is 643.5 kcal

and, the dogs daily protein intake is 41.8275 grams
