Alex is planning his birthday party. He needs 2 gallons of juice for every 15 guests. If Alex expecting 30 guests, how many gallons of juice are required? Round up the answer.
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.
