Answer:
$420
.8 x = 336
x = 336/.8
X=$420
Step-by-step explanation:
Answer:
i`m not very good at maths but i`m pretty sure this is right:
if the original price was reduced by 20%, then $336 is 80%
divide 336 by 8 to get a unit rate of money per 10%
10% = $42
multiply this by 10 to get 100%, or the original price
the original price is $420

There are 2 ways to do this....
(1) 20(1.15) = 23
(2) 20 + 0.15(20) = 20 + 3 = 23
4th root is even so there can be negative solutions.
0.0001
0.001 * 0.1
0.01 * 0.1 * 0.1
0.1 * 0.1 *0.1 * 0.1
4th root (0.0001) = 0.1 or -0.1
