Correct Answer: A
Explanation:
During the first week of September, a shoe retailer sold 10 pairs of a certain style of oxfords at $35.00 a
pair; if, during the second week of September, 15 pairs were sold at the sale price of $27.50 a pair, by
what about did the revenue from weekly sales of these oxfords increase during the second week?
First week revenue = 10 × 35 = 350
Second week revenue = 15 × 27.5 = 412.50
Revenue increase = 412.5 - 350 = 62.50
