If the cost of a shirt remains unchanged, an increase of 20% in the number of shirts sold should be accompanied by an increase of 20% in sales. Since the actual increase in sales was only 14%, Price of shirt on Saturday = 114/120 × $30 = $28.50 Discount percentage = 6/120 × 100% = 5%

Price (new to old) = revenue (new to old) / qty (new to old) = 1.14/1.2 = 0.95. Hence, discount is 5% and new price is 0.95*30 = $28.50.
