In Ms.Morales class, the ratio of boys to girls is 3:7. The class sizes at Ms.Morale’s school range from 22 to 34 students per class. What is the total number of students in Ms.Morale’s class?
for every 3 boys, there are 7 girls. X needs to be higher then 21 and lower then 35, so 21<X>35 X=n×(3+7) X=n×10 n can only be 3 so that X can be 30 X = 3 × 10 = 30 students if n is 4 for example X = 4 × 10 = 40 which is higher than 34
