First Pie Graph: Favorite Pet

We are given percentages for some pets:
- cat: 9%
- spider: 11%
- gerbil: 15%
- dog: 15%
- fish: 28%
- snake: ? (we’ll calculate this)

Total must be 100%. So let’s add up what we know:

9 + 11 = 20
20 + 15 = 35
35 + 15 = 50
50 + 28 = 78

So snake = 100 - 78 = 22%

Now we have all values:
- cat: 9%
- spider: 11%
- gerbil: 15%
- dog: 15%
- fish: 28%
