(Points : 1)

To solve this problem, we need to find out how much 100% lemon juice should be added to the 20% lemon juice and 80% lime juice mixture. Let's break down the steps:

Step 1: Determine the amount of lemon juice in the final mixture:
Since the final mixture is 50% lemon juice, we know that half of the mixture will be lemon juice. Since we want to make 4 gallons of the mixture, this means we need 2 gallons of lemon juice.

Step 2: Subtract the amount of lemon juice already present in the 20% lemon juice and 80% lime juice mixture:
The given mixture is 20% lemon juice and 80% lime juice. If we have 4 gallons of this mixture, we can calculate the amount of lemon juice in it by multiplying the total volume (4 gallons) by the lemon juice concentration (20% or 0.2): 4 gallons x 0.2 = 0.8 gallons of lemon juice.

Step 3: Calculate how much 100% lemon juice needs to be added:
To obtain the desired 2 gallons of lemon juice in the final mixture, we need to subtract the amount of lemon juice already present (0.8 gallons) from the desired amount.
2 gallons - 0.8 gallons = 1.2 gallons of 100% lemon juice needs to be added.

Therefore, the correct answer is B. 1.5 gallons.
