Mr. Johnson's math class has twice as many students as Mrs. Jones' math class. Mr. Smith's math class has 4 more students than Mr. Johnson's math class.
The total number of students in all of the classes is 54 students.
How many students are in Mr. Smith's class?
Hint: Make the number of students in Mrs. Jones class x

Mr Smith: 24

Mr Johnson: 20

Mrs Jones: 10

24+20+10=54

Step-by-step explanation:

So I took a random number, and that number was 24.

I took 24 and put at as my testing in Smith's class.

If Mr. Smith had 24 students then, (x-4=Mr Johnson's class) Mr Johnson has 20 students, and half of that would be the amount of students in Mrs Jones class, so that equals 10.

J = Jones

Jo = Johnson

S = Smith

Finally  S+Jo+J=54
