Help! If you love math, this is my question to you!!!!!?

Question

If a certain brand of coffee is 97% caffeine-free, how many cups of coffee would you have to drink to get the amount of caffeine found in a standard cup of coffee?

Answer 1

since you want 100% divide that by 3%

100%/3%=100/3=33.3333333333333

Answer 2

So, 1 cup of that coffee has 3% of the normal caffeine, and you want to drink enough cups to get 100%.

100% / 3% = 33.33 cups of coffee.
