Step-by-step explanation:
Ariane feeds the kitten twice in the morning and twice in the evening. That's a total of 4 times. If each time she feeds them k grams, she feeds the kitten a total of
![\underbrace{k+k}_{\text{morning}}+\underbrace{k+k}_{\text{evening}} = 4k](https://tex.z-dn.net/?f=%20%5Cunderbrace%7Bk%2Bk%7D_%7B%5Ctext%7Bmorning%7D%7D%2B%5Cunderbrace%7Bk%2Bk%7D_%7B%5Ctext%7Bevening%7D%7D%20%3D%204k%20)

grams of food to the dog.
So, the total is
