+8 Mr. Selan gave his class two tests. 32% of the class passed both tests. and 70% of the class passed the first test. What percent of those who passed the first test also passed the second test? a. about 22% b.about 32% c.about 38% d.about 46%
+23252 One way to do this is to assume that there were exactly 100 students. Since 70% of the students passed the first test, 70 students passed the first test. Since only 32% of the students passed both tests, only 32 students passed both tests. This means that 32 of the original 70 passing students also passed the second test. 32/70 = .46 (approximately) = 46%.
