Answer:
option (c)5 and [tex]\frac{\textup{1}}{\textup{4}}[/tex] cups
Step-by-step 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 = [tex]\frac{\textup{Daily energy intake requirement}}{\textup{Energy present in different brand food}}[/tex]
or
the amount of food required = [tex]\frac{\textup{1,840}}{\textup{3,523}}[/tex]
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 = [tex]\frac{\textup{the amount of food required }}{\textup{Amount of food per cup}}[/tex]
or
the number of cups required = [tex]\frac{\textup{522.28}}{\textup{100}}[/tex]
or
the number of cups required = 5.2228 ≈ 5 and [tex]\frac{\textup{1}}{\textup{4}}[/tex] cups
Hence, the correct answer is option (c)
