You can put this solution on YOUR website! The first thing is to find out how many do take either language.
Since 25 don't take either that means that 80-25 take at least one of them.
55 take at least one of them
30+40 study French and Spanish.
70-55 take both French and Spanish
and 15 take only Spanish and 25 take only French.
I find it hard to believe that more take French than Spanish.
That was true when I went to school back in the dark ages but there are so many more Hispanics now.
