Question

At a school football game, an adult ticket costs $4 and a student ticket costs $1. A total of 250 people attend the game, earning the school $427. How many students attended the game?

Answer 1

Let A = the number of adults; Let S = the number of students

So
$4A + $1S = $427
A + S = 250

So A= 250 - S

Substitute into the first equation

$4(250-S) + $1S = $427

So S = 191 students
