In Mrs. Harrington’s history class, 80% of the students speak English and 60% speak German. There are 30 students who speak only one language. What is the maximum number of students who can speak English and German in his class? so I think I’m supposed to start by finding the total, but I don’t know where to start. can you please show all your steps and why. I doubt there are students who don’t speak any language, so since (80+60) = 140%, 40% speak both English and German.
Thus, 40% speak only English and 20% speak only German.
This means that 60% of students speak only one language.
So, if there are x students,
.60x = 30
x = 50
40% of 50 year olds are 40 year olds who speak both.
