Martin buys a pencil and a notebook for 80 cents. At the same store, Gloria buys a notebook and an eraser for $1.05 cents, and Zachary buys a pencil and an eraser for 65 cents. How many cents would it cost to buy three pencils, three notebooks, and three erasers? (Assume that there is no volume discount.)  Pick:
A) 300
B) 325
C) 350
D) 375
E) 400
pencil + notebook = 80   notebook + eraser = 105   pencil + eraser = 65   Let's add all three equations.   2 pencils + 2 notebooks + 2 erasers = 250 cents   The cost to buy 3 of each would be (3/2)(250) = 375   The answer is 375.
