Beverages at the Store : 2,000 milliliters of soda; 2.5 liters of apple juice; 1500 milliliters of fruit punch; and 2 liters of lemonade.

2. Mandy wants to buy a variety of beverages for her birthday party. She decides to buy 10 liters of beverages. If she buys one container of each beverage, how many more milliliters does she need to buy to have exactly 10 liters?

To begin, we need to convert all the measurements to the same unit. Let's convert everything to milliliters:

- 2,000 milliliters of soda = 2 liters x 1000 = 2000 milliliters
- 2.5 liters of apple juice = 2.5 liters x 1000 = 2500 milliliters
- 1500 milliliters of fruit punch = 1500 milliliters
- 2 liters of lemonade = 2 liters x 1000 = 2000 milliliters

Now we can add up all the milliliters:

2000 + 2500 + 1500 + 2000 = 8000 milliliters

Mandy wants to buy 10 liters, which is 10 liters x 1000 = 10,000 milliliters. So she needs to buy:

10,000 - 8000 = 2000 milliliters

Therefore, Mandy needs to buy an additional 2000 milliliters of beverages to have exactly 10 liters.

To find out how many more milliliters Mandy needs to buy to have exactly 10 liters, we can follow these steps:

1. Convert the given amounts to milliliters:
- 2,000 milliliters of soda remain the same
- 2.5 liters of apple juice is equal to 2.5 * 1000 = 2,500 milliliters
- 1,500 milliliters of fruit punch remain the same
- 2 liters of lemonade is equal to 2 * 1000 = 2,000 milliliters

2. Calculate the total amount of milliliters she already has:
2,000 + 2,500 + 1,500 + 2,000 = 8,000 milliliters

3. Convert the desired amount of beverages (10 liters) to milliliters:
10 * 1000 = 10,000 milliliters

4. Find the difference between the desired amount (10,000 milliliters) and the amount Mandy already has (8,000 milliliters):
10,000 - 8,000 = 2,000 milliliters

Therefore, Mandy needs to buy 2,000 more milliliters of beverages to have exactly 10 liters for her birthday party.

To find out how many more milliliters Mandy needs to buy to have exactly 10 liters of beverages, we need to calculate the total volume of the beverages she already has and then subtract it from 10 liters.

First, let's convert the volumes of the beverages to liters to make the calculations easier:

- 2,000 milliliters of soda is equal to 2 liters (since 1 liter is equal to 1,000 milliliters).
- 2.5 liters of apple juice is already in liters.
- 1,500 milliliters of fruit punch is equal to 1.5 liters.
- 2 liters of lemonade is already in liters.

Now let's calculate the total volume of the beverages Mandy already has:

2 liters (soda) + 2.5 liters (apple juice) + 1.5 liters (fruit punch) + 2 liters (lemonade) = 8 liters.

To find out how many more milliliters Mandy needs to buy, we subtract the total volume of the beverages she already has from 10 liters:

10 liters - 8 liters = 2 liters.

But we want to find the value in milliliters. Since 1 liter is equal to 1,000 milliliters:

2 liters x 1,000 milliliters per liter = 2,000 milliliters.

Therefore, Mandy needs to buy an additional 2,000 milliliters of beverages to have exactly 10 liters.
