a soft drink company had 6000 small and 10000 big bottles in storage . if 12 % of small 15 % of big bottles have been sold , then the total bottles remaining in storage is
"6000 + 10000 - ( 0.12 * 6000 + 0.15 * 10000 ) = 13780 . answer : b ."
subtract(add(6000, 10000), add(multiply(6000, divide(12, const_100)), multiply(divide(15, const_100), 10000)))
