Chaz is a 79.2 pound dog that was just adopted. Based on his foster home his daily energy intake is 1,840 kcal. Chaz’s new owners would like to use a different brand of food that contains 3,523 kcal/kg of food and a cup of food weighs 100grams. how many cups should chaz be fed everyday?

a) 4 and 3/4 cups
b) 6 cups
c) 5 and 1/4 cups
d) 3 and 1/2 cups

Answer 1

option (c)5 and
`\frac{\textup{1}}{\textup{4}}` cups

Explanation:

Given:

Weight of Chaz = 79.2 pounds

Daily energy intake requirement = 1,840 kcal

Energy present in different brand food = 3,523 kcal/kg

Therefore,

the amount of food required =
`\frac{\textup{Daily energy intake requirement}}{\textup{Energy present in different brand food}}`

or

the amount of food required =
`\frac{\textup{1,840}}{\textup{3,523}}`

or

the amount of food required = 0.52228 kg

also,

1 kg = 1000 grams

therefore,

the amount of food required = 0.52228 × 1000 = 522.28 grams

now,

A cup of food weighs 100 grams

hence,

the number of cups required =
`\frac{\textup{the amount of food required }}{\textup{Amount of food per cup}}`

or

the number of cups required =
`\frac{\textup{522.28}}{\textup{100}}`

or

the number of cups required = 5.2228 ≈ 5 and
`\frac{\textup{1}}{\textup{4}}` cups

Hence, the correct answer is option (c)
