Martin buys a pencil and a notebook for 80 cents. At the same store, Gloria buys a notebook and an eraser for 75 cents, and Zachary buys a pencil and an eraser for 35 cents. How many cents would it cost to buy three pencils, three notebooks, and three erasers? (Assume that there is no volume discount.)  Select the correct option:
A) 285  B) 295  C) 305  D) 315  E) 325
pencil + notebook = 80   notebook + eraser = 75   pencil + eraser = 35   Let's add all three equations.   2 pencils + 2 notebooks + 2 erasers = 190 cents   The cost to buy 3 of each would be (3/2)(190) = 285   The answer is 285.
