Answer

# Explanation: ## Step1: Calculate popcorn cost for A $3 \times 5.75 = 17.25$ ## Step2: Calculate popcorn cost for B $3 \times 6.75 = 20.25$ ## Step3: Let n = number of friends. Total cost A: $14.50n + 17.25$ ## Step4: Total cost B: $13.00n + 20.25$ ## Step5: Find break-even n: $14.50n + 17.25 = 13.00n + 20.25$ → $n=2$ ## Step6: For n>2, B cheaper; n<2, A cheaper; n=2, same. "Some friends" implies n>2. # Answer: The friends should choose Theater B. For more than 2 friends, Theater B's lower per-ticket price offsets higher popcorn cost, resulting in lower total cost.
