Final answer:
To find the number of cats in the shelter in May, calculate a 50% increase from the number of cats in February. The answer is 45 cats.
Step-by-step explanation:
To find the number of cats in the shelter in May, we need to calculate a 50% increase from the number of cats in February.
First, we find 50% of 30 cats:
50% of 30 = (50/100) x 30 = 15
Next, we add the increase to the initial number of cats:
30 cats + 15 cats = 45 cats
Therefore, there were 45 cats in the shelter in May.
