1.2b + 35 < 50 b
Subtract 1.2b from both sides:
35 < 50 b - 1.2b
Combine like terms:
35 < 48.8 b
Now, divide both sides by 48.8:
35/48.8 < b
0.7172 < b
Therefore, Youssef could bring a maximum of 0.7172 books on his trip. Since he can't bring a fraction of a book, the maximum number of books he can bring is 0.
