Answer 1

Using a system of equations, it is found that there were 100 students at the bus stop.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

• Variable x: Number of boys in the bus stop.

• Variable y: Number of girls in the bus stop.

Considering the first paragraph, the equation is:

$\frac{x}{y - 25} = \frac{3}{2}$

Considering the second paragraph, the equation is:

y - 25 = x - 15.

Hence:

y = x + 10.

Replacing on the first equation:

$\frac{x}{x - 15} = \frac{3}{2}$

3x - 45 = 2x

x = 45.

y = x + 10 = 55.

The total number was:

45 + 55 = 100.
