Millie wants to take swimming lessons. She can purchase two different swim lesson packages. Package A is 20 lessons for $240. Package B is 15 lessons for $180.

If Millie wants the better buy, which package should she choose?

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

Package A: 20 lessons for $240
Cost per lesson = total cost / number of lessons = $240 / 20 = $12 per lesson

Package B: 15 lessons for $180
Cost per lesson = total cost / number of lessons = $180 / 15 = $12 per lesson

Since both packages have the same cost per lesson ($12), it does not matter which package Millie chooses in terms of price.

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

For Package A:
Total cost = $240
Number of lessons = 20
Cost per lesson = Total cost / Number of lessons = $240 / 20 = $12

For Package B:
Total cost = $180
Number of lessons = 15
Cost per lesson = Total cost / Number of lessons = $180 / 15 = $12

Both Package A and Package B have the same cost per lesson of $12.

Therefore, since the cost per lesson is the same for both packages, Millie can choose either package and it would be the same in terms of cost.

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

For Package A, the cost is $240 for 20 lessons. To find the cost per lesson, divide the total cost by the number of lessons: $240 / 20 = $12 per lesson.

For Package B, the cost is $180 for 15 lessons. Again, to find the cost per lesson, divide the total cost by the number of lessons: $180 / 15 = $12 per lesson.

Both Package A and Package B have the same cost per lesson, which is $12.

Therefore, in terms of cost, both packages are the same. However, if Millie wants more swimming lessons, she should choose Package A, as it offers 20 lessons compared to Package B's 15 lessons.
