Let X be the original price .05X = first discount new price is X-.05X .20(X-.05X) = 2nd discount new price is X -.05X - .20(X-.05X) new price = X - .05X -.20X + .01X = X - .24X equiv discount = .24 = 24%

5x^2 + 40x = 05x(x + 8) = 05x = 0 or x + 8 = 0x = 0 or x = -8Check:
.05x=7474/.05 = xx = 1480100% is 1480, 1/15 is 6.6666% so 6.666% of 1480 = 98.66698.6666
To find the number that, when multiplied by 5%, equals 16000, you need to divide 16000 by 5% (or 0.05). This calculation would be 16000 / 0.05 = 320000. Therefore, the number you are looking for is 320000.
