A mixture contains 25% of substance A and 75% of substance B. If the total weight of the mixture is 200 grams, how much of substance B is present?

Step 1: Understand that the mixture is made up of two substances: A and B.
Step 2: Note the percentages of each substance in the mixture: 25% is substance A and 75% is substance B.
Step 3: Identify the total weight of the mixture, which is given as 200 grams.
