Q: The maximum safe amount of caffeine you can consume per day is 500 mg. If each energy drink has 120 mg of caffeine and Brandy drinks 4 of them, how much more caffeine can she safely consume that day?
A: First find the total amount of caffeine Brandy already drank: 120 mg / drink * 4 drinks = 480 mg. Then subtract that amount from the amount it's safe to consume daily to find the remaining amount Brandy can consume: 500 mg - 480 mg = 20 mg. The answer is 20.
