Answer:
Step-by-step explanation:
Let x represent the discount in percentage offered for the price of the shirts.
The regular price of the shirts was $20
The price for which the shirt was offered for sale is $17 which also represents the discounted price.
The discount would be
20 - 17 = $3
The percentage discount would be
The discount/ the regular price × 100%.
Therefore,
% discount = 3/20 × 100 = 0.15 × 100
= 15%
