Answer:
15 calories
Explanation:
Number of calories in 8 ounces of orange juice = 100
Number of calories in 1 ounce of juice = 100/8
Number of calories in 4 ounces of juice = 100/8 x 4 = 50 calories
Number of calories in 8 ounces of pineapple juice = 140
Number of calories in 1 ounce of juice = 140/8
Number of calories in 4 ounces of pineapple juice= 140/8 x 4 = 70 calories
Now the mixture has 50 + 70 = 120 calories in 8 ounce.
So, 1 ounce of mixture has 120/8= 15 calories.
