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 3 pencils, 3 notebooks, and 3 erasers? ( assume that there is no volume discount. )
multiply(divide(add(add(multiply(1.15, const_100), 80), 75), const_2), 3)
