if the price of a certain computer increased 30 percent from d dollars to 338 dollars , then 2 d =
"before price increase price = d after 30 % price increase price = d + ( 30 / 100 ) * d = 1.3 d = 338 ( given ) i . e . d = 338 / 1.3 = $ 260 i . e . 2 d = 2 * 260 = 520 answer : option b"
multiply(divide(338, divide(add(const_100, 30), const_100)), 2)
