			double ratioPay = 1;
			int numPercOff = stdin.nextInt();
			for (int i=0; i<numPercOff; i++)
				ratioPay *= ((100.0-stdin.nextDouble())/100.0);

			// Be greedy here, first apply the percentage off, then the straight discounts.
			// Reason: Let p = ratio discount and q = subtractive discount. Two options for original price x are:
			//         (1) (x - q)p = px - pq, or (2) px - q, since p < 1, pq < q, so the second option subtracts more.
			System.out.printf("%.2f\n", price*ratioPay - dollarsOff);
