Final answer:
To determine the better buy, compare the cost per lesson for package A and package B. Package B is the better buy because it offers a lower cost per lesson.
Step-by-step explanation:
To determine which swim lesson package is the better buy, we need to compare the cost per lesson for package A and package B.
Let's say package A costs $100 for 5 lessons, while package B costs $150 for 10 lessons. In package A, each lesson would cost $20, whereas in package B, each lesson would cost $15.
Therefore, package B is the better buy because it offers a lower cost per lesson.
