Some of the students at Georgia Middle School like to walk to and from school. They always walk unless it rains. Let d be the distance in miles from a student's home to the school. Write two different expressions that represent how far a student travels by walking in a two week period if there is one rainy day each week.
Expression 1: The student walks d miles to school and d miles back home each day. In a two-week period with one rainy day each week, the student walks (10 - 2) * 2d = <<(10-2)*2=16>>16d miles.
Expression 2: The student walks d miles to school and d miles back home each day. In a two-week period with one rainy day each week, the student walks (10 - 2) * (2d + d) = <<(10-2)*(2+1)=24>>24d miles.
