if the price of a certain computer increased 20 percent from d dollars to 351 dollars , then 2 d =
"before price increase price = d after 30 % price increase price = d + ( 20 / 100 ) * d = 1.2 d = 351 ( given ) i . e . d = 351 / 1.3 = $ 292,5 i . e . 2 d = 2 * 292.5 = 585 answer : option b"
multiply(divide(351, divide(add(const_100, 20), const_100)), 2)
