Final answer:
To fill a 20-gallon jug with an energy drink using the ratio of 1 cup of mix for every 2 gallons of water, 10 cups of mix are needed.
Step-by-step explanation:
The question is asking about how many cups of mix are needed to fill a 20-gallon jug with an energy drink. Given that 1 cup of mix is needed for every 2 gallons of water, we need to calculate the total number of cups required for 20 gallons. First, we find the number of sets of 2 gallons in 20 gallons, which is 20 / 2 = 10. Now, since each set of 2 gallons requires 1 cup of mix, we multiply the number of sets by the cups per set: 10 sets × 1 cup/set = 10 cups of mix.
