How many sandwiches did Ruth's two cousins eat? ** Ruth's two cousins ate a total of 2 x 1 = <<2*1=2>>2 sandwiches.
How many sandwiches were left before Ruth's two cousins arrived? ** So there were 3 + 2 = <<3+2=5>>5 sandwiches left before her two cousins arrived.
How many sandwiches were there before Ruth's first cousin arrived? ** Before her first cousin arrived, there were 5 + 2 = <<5+2=7>>7 sandwiches.
How many sandwiches did Ruth and her brother have altogether? ** Ruth and her brother had 1 + 2 = <<1+2=3>>3 sandwiches altogether.
How many sandwiches did Ruth prepare? ** Therefore, Ruth prepared 7 + 3 = <<7+3=10>>10 sandwiches."
