Question

Jacob the dog eats dry food that contains 324kcal/cup. Jacob eats 3.5 cups a day. The food contains 3.6 g of fat in 100 kcals of energy. what is his daily fat intake?

the food contains 25.6 IU of Vitamin D3 in 100 kcals of energy. what is his daily Vitamin D inake?

Answer 1

His daily fat intake is 40.824g.

His daily Vitamin D intake is 290.304 IU.

Explanation:

The first step to solve this problem is finding the daily kcal intake of the dogs.

Each cup has 324 kcal, and he eats 3.5cups a day. So:

1 cup - 324 kcals

3.5 cups - x kcals

`x = 324*3.5`

`x = 1134` kcals.

His daily intake is of 1134 kcals.

The food contains 3.6 g of fat in 100 kcals of energy. what is his daily fat intake?

There are 3.6g of fat in 100 kcals of energy. How many g of fat are there in 1134 kcals?

3.6g - 100 kcals

xg - 1134 kcal

`100x = 1134*3.6`

`x = (1134*3.6)/(100)`

`x = 11.34*3.6`

`x = 40.824`g

His daily fat intake is 40.824g.

The food contains 25.6 IU of Vitamin D3 in 100 kcals of energy. what is his daily Vitamin D inake?

Similar logic as above.

25.6IU - 100 kcals

x IU - 1134 kcal

`100x = 1134*25.6`

`x = (1134*25.6)/(100)`

`x = 11.34*25.6`

`x = 290.304`IU

His daily Vitamin D intake is 290.304 IU.
