Question

There are 442 boy students in class

b. if 15% of the students are girls, find the total number of students in class b

Answer 1

520

Explanation:

This problem is

boys + girls = total

Boys = 442

Girls = 15% of the total

Therefore, substituting in, gives us:

442 + .15t = t, where t is total

Then 442 = .85t and

t = 520
