Answer:
Option B
Explanation:
How to find K:
We know the kitten is 3 pounds less than 1/2 the weight of Callie the cat, so we could write the expression as: 1/2c - 3
Proof: "less than = subtraction", "half the weight of Callie's cat" = 1/2c
The second equation on option B (I didn't know what to call this):
In the problem, it says "Together, the cat and the kitten weigh 18 pounds." Therefore, we know C+K = 18. (C being the weight of Callie's cat and K being the weight of the kitten)
I hope this helps! :)
