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

### Instruction:
Jackson is clearing out his email inbox after noticing he has a whole lot of emails that he no longer needs and can delete. While he is cleaning his inbox, though, he keeps getting more emails. While he deletes 50 emails he gets another 15 sent to him. While he deletes 20 more he receives 5 more emails. After he is done deleting all his old emails he has just the new emails left, including 10 more that were sent to him. How many emails are there in Jackson's inbox now?

### Response:
 แจ็กสันลบอีเมลเก่าทั้งหมดแล้วดังนั้นเขาเหลือเพียงอีเมลใหม่เท่านั้น ซึ่งเขาได้รับอีเมลใหม่ 15 + 5 = 20 อีเมล
จากนั้นแจ็กสันได้รับอีเมลเพิ่มอีก 10 อีเมลเข้ามา ทำให้มีอีเมลใหม่ทั้งหมด 20 + 10 = 30 อีเมล
