Answer:
Approximately 30 bottles of lemonade could the concession sell before they run out of lemonade.
Explanation:
Consider the provided information.
A container holds 4 gallons of lemonade.
A bottle of lemonade holds one half of a liter.
1 Liters = 0.264172 gallons
So 1/2 liter = 0.132086 gallons
That means a bottle contains 0.132 gallons of lemonade.
1 bottle = 0.132 gallons
Multiply both the sides by 30
30 bottle = 3.96 gallons (Which is just less than 4 gallons)
That means approximately 30 bottles of lemonade could the concession sell before they run out of lemonade.
Note: We can't take 31 bottles as 0.132×31 = 4.092 which is more than 4 gallons.
