A company needs to select a new vendor based on three criteria: Unit Price must be less than or equal to $50, Delivery Time must be less than or equal to 4 days, and Customer Service Rating (out of 100) must be greater than or equal to 85. Four potential vendors have the following attributes: Vendor P: Price $45, Delivery 3 days, Rating 90. Vendor Q: Price $48, Delivery 5 days, Rating 88. Vendor R: Price $52, Delivery 3 days, Rating 92. Vendor S: Price $40, Delivery 4 days, Rating 80. Which vendor(s) meet all of the company's selection criteria?
✓ Correct Answer: Option A
Vendor P meets all (45<=50, 3<=4, 90>=85). Vendor Q fails delivery (5>4). Vendor R fails price (52>50). Vendor S fails rating (80<85). Thus, only Vendor P meets all criteria.
