Answer:
approximately 30%
Explanation:
Find the discount first: $136 - $95.50 = $40.50
Next, find the fraction of the regular price represented by this discount:
$40.50
------------ = 0.298
$136
The original price ($136) is discounted by approximately 30%.
Check: (1 - 0.30)(regular price) = 0.70($136) = $95.20 which is almost but not precisely the same as the given sale price ($95.50).
