Answer: The required expression is,
4k + 2d
Step-by-step explanation:
Given,
She feeds her kitten k gram of food,
She feeds 2 times in the morning,
⇒ Food fed in morning = 2k,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = 2k,
So, the total food she gives to her kitten = 2k + 2k = 4k,
Now, She feeds her dog d gram of food,
She feeds 1 times in the morning,
⇒ Food fed in morning = d,
Also, she feeds 2 times in the evening,
⇒ Food fed in evening = d,
So, the total food she gives to her dog = d + d = 2d,
Hence, the total food she feeds to her animal in a day = 4 k + 2 d
