a soft drink company had 6000 small and 15000 big bottles in storage . if 11 % of small 12 % of big bottles have been sold , then the total bottles remaining in storage is
"6000 + 15000 - ( 0.11 * 6000 + 0.12 * 15000 ) = 18540 . answer : e ."
subtract(add(6000, 15000), add(multiply(6000, divide(11, const_100)), multiply(divide(12, const_100), 15000)))
