Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Brenda is a vet who needs to spay some cats and twice as many dogs. If she needs to spay 21 animals total today, how many cats does she need to spay?Let c be the number of cats Brenda needs to spay and d be the number of dogs. We know that c + d = 21 and d = 2c.
Substituting the second equation into the first, we get c + 2c = 21
Combining like terms, we get 3c = 21
Dividing both sides by 3, we get c = 7

Tim watches 2 shows.  One of them is a half-hour show per episode and the other is a 1-hour long show per episode.  The short show had 24 episodes and the long show had 12 episodes.  How many hours of TV did he watch?The short show has 24*.5=<<24*.5=12>>12 hours of TV
The long show is 12*1=<<12*1=12>>12 hours
So in total he watches 12+12=<<12+12=24>>24 hours
#### 24[END]
