the price of a shirt is increased by 15 % and then reduced by 15 % . the final price of the shirt is ?
let the original price be $ 100 new final price = 85 % of ( 115 % of $ 100 ) = 85 / 100 * 115 / 100 * 100 = $ 97.75 answer is a
multiply(multiply(subtract(const_1, divide(15, const_100)), add(const_1, divide(15, const_100))), const_100)
