19) In a class of 200 students, 120 students take Italian, and 100 study Spanish. If a student must study at least one of these languages, what percent of the students study Spanish but not Italian?

1. 80%
2. 60%
3. 40%
4. 20%
5. This cannot be determined by the information given.

Since 100 + 120 = 220, we know that 20 students are studying both languages. Thus of the 100 who study Spanish, 80 do not study Italian. 80 is 40% of the total 200.
