Millie wants to take swimming lessons. She can purchase two different swim lesson packages. Package A is 20 lessons for $230. Package B is 15 lessons for $180. If Millie wants the better buy, which package should she choose? Show your work and explain why your choice is the better buy

Answer 1

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

For package A, Millie gets 20 lessons for $230. To calculate the cost per lesson, we divide the total cost by the number of lessons:

Cost per lesson for package A = $230 / 20 lessons = $11.50/lesson

For package B, Millie gets 15 lessons for $180. To calculate the cost per lesson, we divide the total cost by the number of lessons:

Cost per lesson for package B = $180 / 15 lessons = $12/lesson

Comparing the cost per lesson, we see that package A offers a better deal at $11.50 per lesson compared to package B which is $12 per lesson.

Therefore, Millie should choose package A as it offers a better buy with a lower cost per lesson.

Answer 2

you divide the number of milliliters by 1000. So, to convert 3,200 milliliters to liters, you would do the following calculation: 3,200 milliliters ÷ 1000 = 3.2 liters Therefore, the correct answer is option b. 3.2.
