Tammy is making 5 batches of punch for the schools Spring Carnival. The recipe for one batch uses 1 liter of orange juice, 550 mL of lemon juice, 2.6 liters of soda water, and two 750 mL bottles of apple cider. How much punch will she make?

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.
