4 gallons of juice are required
Step-by-step explanation:
He needs 2 gallons of juice for 15 guests.
He is expecting double the guests, so he need double gallons of juice.
2 gallons * 2 = 4 gallons
4 gallons. 2 gallons of juice for every 15 guests would mean that for the first 15 people that show up would be 2 gallons of juice, for the second 15 people so show up would be another 2 gallons. 2+2 is 4. 15+15 is 30.
The answer would be a. 4 gallons

15 = (78+x) / 6
90 = 78+x
x = 90-78
x = 12
