يحاول جيمس تعلم قلع أوراق الألعاب. يمكنه قلع 30 ورقة في وقت واحد. تحتوي还未عة جديدة من الأوراق على 55 ورقة إذا شملت الأوراق الشرسة والأوراق الفارغة. يقلع الأوراق 3 مرات في الأسبوع. إذا اشتراakedirsا一堆，则他能持续多少周؟

The last sentence doesn't translate perfectly due to differences in English and Arabic grammar, but as close as I can get it is:

"إذا اشترا一堆 من هذه ال:resultستضاف, كم أسبوعا يمكنه أن يستمر؟"

But a more natural translation would probably be:

"إذا اشتراكدürتايس 18 واجهة، كم أسبوعًا يستطيع المضي قدماً؟"

But technically this last sentence would usually only be used if he wasn't going to buy more decks after the initial 18, assuming he's able to continue his habit indefinitely as long as he has decks to tear. If you want to stick close to the original English meaning, it would probably be something like:

"إذا اشتراكردُهيمز 18.Decksكم عدد الأسابيع التي يمكنه القيام بها؟"

But again, this doesn't sound as natural in Arabic.
 

 sidenote: The phrase "go" in this context is usually translated in arabic with motion verbs like متابعة or الاستمرار. but "go" here should be understood as "how long can he continue", so the timing duration might suggest using "go" as a suitable verb but "go" is not the usual fit in arabic for such context>

A preferred accurate translation could be "كم عدد الاسبوعrokيسقري咸阳r or الاستمرار?"  however, it will sound odd and out of context as noone will ask such a question, context will always point to the correct units of time which is weeks here. So, a more suitable translation would be like this: 

إذا اشتراكردُهيمز ١٨quetموقد。كم عدد الاسبوعrل imzet c ResultSet لمتابعة قلع الأوراق؟

But again, this is word-for-word translation, which is why understanding the correct meaning is recommended.

To summarize, the most suitable translation would be:

"إذا اشتراكدutherlandcrd
يقطع 30 * 3 = 90 كارت في الأسبوع 
اشترى 55 * 18 = 990 كارت 
لذا يمكنه القاطعه لمدة 990 / 90 = 11 أسبوع
