Question 1101768
<br>
To me, at least, "successive discounts" clearly means the second discount is on the already discounted price....<br>
When the price is discounted 20%, 80% of the price remains.  If the original price is x, then the discounted price after the first discount is 0.80x.<br>
When THAT price is reduced by 12%, 88% of it remains.  The price after the second discount is {{{0.80x * 0.88 = 0.704x}}}<br>
The new price is 70.4% of the original price; the effective discount is 100-70.4 = 29.6%.
