Assume Bill ran x miles on Saturday.
Therefore he ran x + 4 miles on Sunday.

Miles run by Julia on Saturday = 0
Miles run by Julia on Sunday = 2(x + 4) = 2x + 8

Total miles run by Julia and Bill = x + x+4 + 0 + 2x + 8 = 4x + 12
Given 4x + 12 = 24
Hence x = 3

Therefore Bill ran 3 + 4 = 7 miles on Sunday
Option C
