alvin wants to become a hairdresser he can save 250 a month for two years and his family promised to help him with the rest his traing will cost 9,500 how much will his family have to pay
Alvin wants to save for two years, so he will save for a total of 2 years * 12 months/year = <<2*12=24>>24 months.
Therefore, Alvin will save a total of $250/month * 24 months = $<<250*24=6000>>6000.
The remaining amount that his family will have to pay is $9,500 total cost - $6,000 saved by Alvin = $<<9500-6000=3500>>3500. Answer: \boxed{3500}.
