Tammy is making 5 batches of punch for the school's spring carnival. the recipe for one batch uses 1 liter of orange juice, 550 milliliters of lemon juice, 2.6 liters of soda water, and two 750 milliliter bottles of apple cider. how much punch will she make?

Alright, so look. This is one of the probably many ways you can do this. And this is how I used to do my stuff. So watch:

First change the mL to liters:
Orange Juice: 1L
Lemon juice: 550mL=0.55L
Soda Water: 2.6L
Apple cider: 2*750=1500mL=1.5L

Then add them all together:
1+0.55+2.6+1.5=5.65

Lastly, multiply that number by 5:
5.65*5=28.25

Tammy will make 28.25 Liters of punch.

So Answer = 28.25 liters of punch
