There are 4 tickets that cost x dollars each. (4x)
There is a 1.50 dollar purchasing fee for each. (4 x 1.50 = 6)
This means that the left side of the equation would be 4x + 6.
(The price of the tickets plus the purchase fee.)
The right side would be the total cost. (38)
Your equation would be:
Subtract the six from both sides.
Divide by 4.
Each ticket costs 8 dollars.
