### Instruction:
Bronson decides to collect Oak Leaves from around his Neighborhood. He collects 12 on Thursday and 13 on Friday. 20% are Brown and 20% are Green. The rest are yellow. How many yellow leaves does he collect?

### Response:
He collects 25 leaves because 12 + 13 = <<12+13=25>>25
60% of them are yellow because 100 - 20 - 20 = <<100-20-20=60>>60
He collects 15 yellow leaves because 25 x .6 = 15
#### 15
