question: Luke is buying fabric for new curtains. There are five windows. Each window is 35 inches wide and Luke needs to buy fabric equal to 2 times the total width of the windows. How much fabric should he buy?
answer: The total width of the five windows is 35 x 5 = <<35*5=175>>175 inches.
  Luke needs to buy 175 x 2 = <<175*2=350>>350 inches of fabric.
