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?

How much caffeine did Brandy drink? ** First find the total amount of caffeine Brandy already drank: 120 mg/drink * 4 drinks = <<120*4=480>>480 mg
How much more caffeine can Brandy safely consume that day? ** 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 = <<500-480=20>>20 mg
