### 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:
 เขาเก็บใบโอ๊คทั้งหมด 25 ใบเพราะ 12 + 13 = <<12+13=25>>25
60% ของใบโอ๊คเป็นสีเหลืองเพราะ 100 - 20 - 20 = <<100-20-20=60>>60
เขาเก็บใบโอ๊คสีเหลือง 15 ใบเพราะ 25 x .6 = <<15=15>>15
