Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
Tracy has been collecting novels from her friends to donate to the Children For The Future charity organization. In the first week she collects a certain number of books. In the next five weeks, she collects ten times as many books as she did in the first week. How many books did she collect in the first week if she has 99 books now?

### Response:
 ในสัปดาห์แรก เธอรวบรวม <<99/11=9>>9 เล่ม
ในสัปดาห์ถัดไปห้าสัปดาห์ เธอรวบรวม 5*10*9=<<5*10*9=450>>450 เล่ม
ดังนั้น เธอมีหนังสือทั้งหมด 9 + 450 = <<9+450=459>>459 เล่มในปัจจุบัน
