Final answer:
The difference between the number of adult cats on Wednesday and Saturday is 5, determined by first calculating the number of adult cats on Saturday using the given ratio and then finding the difference.
Step-by-step explanation:
To determine the difference between the number of adult cats on Wednesday and Saturday at the pet care center, we first need to use the given ratio of adult cats to kittens and find out how many adult cats correspond to 18 kittens on Saturday.
The ratio is given as 4 adult cats for every 3 kittens. If there were 18 kittens, we can set up a proportion to calculate the number of adult cats:
- First, divide the number of kittens by the kitten part of the ratio: 18 kittens ÷ 3 = 6.
- Then multiply this result by the adult cat part of the ratio to get the number of adult cats: 6 × 4 = 24 adult cats.
- On Saturday, there were 24 adult cats. We're told that on Wednesday there were 29 adult cats.
- To find the difference, subtract the number of adult cats on Saturday from the number of adult cats on Wednesday: 29 - 24 = 5.
So, the difference between the number of adult cats on Wednesday and Saturday is 5 adult cats (Option a).
