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

For Package A, the cost per lesson is given by:

Cost per lesson in Package A = Total cost of Package A / Number of lessons in Package A
= $230 / 20 lessons
= $11.50 per lesson

For Package B, the cost per lesson is given by:

Cost per lesson in Package B = Total cost of Package B / Number of lessons in Package B
= $180 / 15 lessons
= $12.00 per lesson

Comparing the cost per lesson, we can see that Package A has a lower cost per lesson ($11.50) compared to Package B ($12.00).

Therefore, Millie should choose Package A as it offers a better buy.
