If it takes 10 bags of rice to feed a family of 5 for 35 days, then 1 bag of rice feeds the family for 35/10 = <<35/10=3.5>>3.5 days.
To feed the family for 50 days, they would need 50/3.5 = <<50/3.5=14.285714285714286>>14.285714285714286 bags of rice.
Since they cannot buy a fraction of a bag of rice, the family would need 15 bags of rice to feed them for 50 days. Answer: \boxed{15}.
