To convert milliliters to liters, you divide the number of milliliters by 1,000.

So, for 3,200 milliliters, you would divide 3,200 by 1,000:

3,200 mL / 1,000 mL/L = 3.2 liters.

Therefore, there are 3.2 liters in 3,200 milliliters.

To convert gallons per hour to liters per minute, you need to perform two conversions. First, convert gallons to liters, and then convert hours to minutes.

Given:
24 gallons per hour
3.78 liters per gallon
60 minutes per hour

To convert gallons to liters, you multiply the number of gallons by the conversion factor of 3.78:
24 gallons * 3.78 liters/gallon = 90.72 liters

To convert hours to minutes, you multiply the number of hours by the conversion factor of 60:
1 hour * 60 minutes/hour = 60 minutes

Now, divide the liters by the minutes to determine the rate in liters per minute:
90.72 liters / 60 minutes = 1.512 liters per minute

Therefore, 24 gallons per hour is approximately equal to 1.512 liters per minute.

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.(4 points)

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

For Package A:
Cost: $230
Number of lessons: 20

Cost per lesson = $230 / 20 = $11.50 per lesson

For Package B:
Cost: $180
Number of lessons: 15

Cost per lesson = $180 / 15 = $12 per lesson

Based on the calculations, Package A has a lower cost per lesson ($11.50) compared to Package B ($12). Therefore, Millie should choose Package A because it offers a better deal in terms of cost per lesson.
