Answer:
For 4 times the original recipe Lebron needs 12 cups of cranberry juice with 8 cups of apple juice.
Explanation:
For 5 cups of punch Lebron needs 3 cups of cranberry juice with 2 cups of apple juice.
For 4 times the original recipe Lebron needs 3*4= 12 cups of cranberry juice with 2*4= 8 cups of apple juice.
He will get 20 cups of punch.
We multiply each ingredient of the original recipe by the factor 4 to get the required ingredients of the 4 times product as the original product.
