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

### Instruction:
Tony's dad is very strict about the washing machine and family members are only allowed to wash 50 total ounces of clothing at a time. Tony doesn't want to break the rules, so he weighs his clothes and finds that a pair of socks weighs 2 ounces, underwear weighs 4 ounces, a shirt weighs 5 ounces, shorts weigh 8 ounces, and pants weigh 10 ounces. Tony is washing a pair of pants, 2 shirts, a pair of shorts, and 3 pairs of socks. How many more pairs of underwear can he add to the wash and not break the rule?

### Response:
 เสื้อผ้าของทอนี่มีน้ำหนัก 10 + 10 + 8 + 2 + 4 = <<10+10+8+2+4=34>>34 ออนซ์
ทอนี่สามารถซักอีก 50 - 34 = <<50-34=16>>16 ออนซ์
ชุดชั้นใน 1 คู่มีน้ำหนัก 4 ออนซ์ ดังนั้นทอนี่สามารถซักชุดชั้นในอีก 16 / 4 = <<16/4=4>>4 คู่
