Answer:
10 cups of fertilizer
Step-by-step explanation:
2 cups fertilizer = 12 quarts water
so, 1 cups fertilizer means = 12/2 = 6 quarts of water
Now, 15 gallons to quarts would be:
4 quart = 1 gallons
So,
15 gallon = 4 * 15 = 60 quarts
So, we are essentially asking:
How many cups of fertilizer we need for 60 quarts
The ratio is 1 cup = 6 quarts
So, 60/6 = 10 cups is 60 quarts
We would need 10 cups of fertilizer to make 15 gallons of mixture
