14. According to a recent government study, the average 15-year-old male gets 11.4% of his daily caloric intake from sugar drinks.If that 15-year-old consumes 2,400 calories each day, how many calories come from sugar drinks?

Answers

The calories come from sugar drinks = 269.76 calories

Step-by-step explanation:

  • Daily caloric intake from sugar drinks = 11.4%
  • Total calories consumed each day = 2400

Calories come from sugar drinks = 11.4% of 2400

⇒ (11.4/100)*2400

⇒ 11.4*24

⇒ 269.76 calories.

∴ Calories come from sugar drinks is 269.76 calories.
