Answer:
$46.24
Explanation:
$68 is the original price
First, take off 20%
68*0.2 = $13.60 - - - that's the first discount.
So 68-13.60 = 54.40 === that's the price after the first discount of 20%.
Now we need to take off 15%.
54.4 * 0.15 = 8.16 - - - - that's the 2nd discount.
54.4 - 8.16 = 46.24
Another quick way is 68(1-0.2) * (1-0.15) = 46.24
