Jeff has a shelter where he currently takes care of 20 cats. On Monday he found 2 kittens in a box and took them to the shelter. On Tuesday he found 1 more cat with a leg injury. On Wednesday 3 people adopted 2 cats each. How many cats does Jeff currently have in his shelter?
Let's be accurate as possible. Think before you answer.
17
Counting the cats he had, the kittens he found, and the injured cat, Jeff had a total of 20 + 2 + 1 = 23 cats.

3 people took a total of 3 * 2 = 6 cats.

After Wednesday, Jeff was left with 23 - 6 = 17 cats.

.

Thus, the answer is 17
