Answer :
There are 315 calories in 21 oz of the energy drink. This is calculated by finding the number of calories per ounce, which is 15, and then multiplying by 21.
To find out how many calories are in 21 oz of the energy drink when 7 oz contains 106 calories, you can set up a proportion or use a unit rate. If 7 oz has 106 calories, then 1 oz has 106 calories divided by 7. Therefore, to find the calories in 21 oz, multiply the calories per ounce by 21.
- Calculate calories per ounce: 106 calories / 7 oz = 15 calories/oz.
- Calculate calories in 21 oz: 15 calories/oz * 21 oz = 315 calories.
There are 315 calories in 21 oz of the energy drink.
