Given is asked to supply juice to a soccer team during half time and he decides to make the juice from a concentrate mix. If each soccer player needs to drink 300mL of juice, how many litres of juice does Gavin need to mix for 30 players

If each soccer player needs to drink 300mL of juice, then the total juice needed for 30 players is 300mL x 30 players = <<300*30=9000>>9000mL.

Since 1 liter is equal to 1000mL, then there 9000mL ÷ 1000mL = <<9000/1000=9>>9 liters of juice needed. Answer: \boxed{9}.

To calculate the amount of juice Gavin needs to mix for 30 players, we need to find the total volume required.

Since each player needs to drink 300 mL of juice, we can multiply the volume by the number of players to get the total volume:

300 mL/player * 30 players = 9000 mL

To convert this to liters, we need to divide by 1000 mL/L:

9000 mL ÷ 1000 mL/L = 9 L

Therefore, Gavin needs to mix 9 liters of juice for 30 players.

To determine the amount of juice Gavin needs to mix, we need to calculate the total volume required for all 30 players. Here's how we can do it:

1. Calculate the total volume required:
300 mL per player * 30 players = 9000 mL

2. Convert the volume from milliliters (mL) to liters (L):
9000 mL ÷ 1000 = 9 L

Therefore, Gavin needs to mix 9 liters of juice for the soccer team during halftime.
