Martin buys a pencil and a notebook for 80 cents. At the same store, Gloria buys a notebook and an eraser for $1.15 cents, and Zachary buys a pencil and an eraser for 75 cents. How many cents would it cost to buy three pencils, three notebooks, and three erasers? (Assume that there is no volume discount.) Choose the correct choice from the following answers.
A) 325
B) 345
C) 365
D) 385
E) 405
pencil + notebook = 80   notebook + eraser = 115   pencil + eraser = 75   Let's add all three equations.   2 pencils + 2 notebooks + 2 erasers = 270 cents   The cost to buy 3 of each would be (3/2)(270) = 405   The answer is 405.
