Question

120 people attended the baseball game. Adults cost $6 and students cost $4 to attend the game. The game raised $600 from the attendance. How many students attended the game?

Answer 1

A + S=120
6A +4S = 600

Use substitution A= 120-S


6(120-S) + 4s = 600

720 -6S + 4S = 600
720 -2S = 600

Can you finish from here?

Answer 2

a = numbers of adults

s = number of students


120 people attended the baseball game mean:

a + s = 120


Adults cost $6 and students cost $4 to attend the game.

The game raised $600 from the attendance mean:

a * &6 + s * $4 = $600

OR

6 a + 4 s = 600


Now you must solwe system:

a + s = 120

6 a + 4 s = 600

Try to solve this system.


The solutions are:

a = 60 , s = 60


Proof:

a + s = 60 + 60 = 120

6 a + 4 s = 6 * 60 + 4 * 60 = 360 + 240 = 600
