Give the step-by-step reasoning process and then the final answer. 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?
User
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 final answer: 20.
