Question: Ruth prepared sandwiches. She ate 1 sandwich and gave 2 sandwiches to her brother. Her first cousin arrived and ate 2 sandwiches. Then her two other cousins arrived and ate 1 sandwich each. There were 3 sandwiches left. How many sandwiches did Ruth prepare? Is final answer 10?
Answer: Ruth's two cousins ate a total of 2 x 1 = <<2*1=2>>2 sandwiches.
So there were 3 + 2 = <<3+2=5>>5 sandwiches left before her two cousins arrived.
Before her first cousin arrived, there were 5 + 2 = <<5+2=7>>7 sandwiches.
Ruth and her brother had 1 + 2 = <<1+2=3>>3 sandwiches altogether.
Therefore, Ruth prepared 7 + 3 = <<7+3=10>>10 sandwiches."
