based on the information in the table, at which store will christopher pay the least for 6 chairs?

Explanation:

Step1: Calculate total for Store A

Price per chair: $120, discount $40 per chair. So effective price per chair: $120 - $40 = $80. For 6 chairs: $80 * 6 = $480.

Step2: Calculate total for Store B

Price per chair: $150, 6 chairs total before discount: $150 * 6 = $900. Discount $350, so total: $900 - $350 = $550.

Step3: Calculate total for Store C

Buy 2, get 3rd free. For 6 chairs: every 3 chairs, pay for 2. Number of sets: 6 / 3 = 2 sets. Pay for 2 2 = 4 chairs. Price per chair $220, total: $220 4 = $880.

Step4: Calculate total for Store D

Price per chair: $110, 6 chairs total: $110 6 = $660. 20% off, so pay 80%: $660 0.8 = $528.

Answer:

A. Store A
