Worked Solution
Step 1: Find the rate per minute. Rate = total bottles ÷ total minutes = 240 ÷ 8 = 30 bottles per minute.
Step 2: Apply the rate to the new time. Bottles in 15 minutes = rate × time = 30 × 15 = 450 bottles.
Check (reverse): 450 bottles ÷ 15 minutes = 30 bottles per minute ✓, and 30 × 8 = 240 ✓.
Final answer: 450 bottles.
Answer: 450
Correct answer: 450
