in the event that they have been discounted 20%, which potential you paid 80% of the unique value. $24 = 80%(X) 24 = 0.8X X = 24/0.8 X = 30 Double-examine: $30 * 20% = $6 Subtracting $6, you get $24, as predicted. answer: the unique value replace into $30.

$24 must be 80% of the original cost of the shoes because they were discounted 20%. Therefore, if C represents the original cost, C times .80 = $24, so C = $24 / .80 or $30, which is the original cost.
(fyi - the discount is $6).

Original price = c
80% of c = $24
0.8 c = $24
c = $24/0.8
c = $30
Easier with fractions.
$24 is 4/5 of c
24 = 4/5 c
24 * 5/4 = c
30 = c

Let X equal the original price.
Therefore, (0.8)(X) = 24
X = 24/0.8 = 30

$30,00.
20% of $30.00 is $6.00
30 - 6 = 24.00
