Answer:
Physics: 190.5
Chemistry: 272.5
Step-by-step explanation:
We know that there are two classes whose numbers were combined so we can start off by dividing 463 by 2 to get 231.5. The physics textbook sold 41 less textbooks so we subtract 41 from 231.5 to get 190.5. Subtract 190.5 from 463 to get the number of chemistry books sold.
