To find the better buy, we need to determine the cost per lesson for each package.

For Package A:
Cost: $230
Number of lessons: 20
Cost per lesson: $230 / 20 = $11.50

For Package B:
Cost: $180
Number of lessons: 15
Cost per lesson: $180 / 15 = $12.00

So, based on the cost per lesson, Package A is the better buy for Millie as it offers a lower cost per lesson ($11.50) compared to Package B ($12.00).
