Question

The number of students taking classes at RSM branch A is 1/4 more than the number of students taking classes at RSM Branch B. If Branch A has 1650 students, how many students does Branch B have?

Answer 1

The number of students is an illustration of a linear function

There are 1320 students in branch B

How to determine the number of students

From the question, we have the following equation that represents the  number of students in branch A

A = 1650

Also, we have:

$A = B + \frac 14B$

Multiply through by 4

$4A = 4B + B$

Add 4B and B

$4A = 5B$

Substitute 1650 for A

$4*1650 = 5B$

$6600 = 5B$

Divide through by 5

$B = 1320$

Hence, there are 1320 students in branch B
