Answer:
Equation: 154=7x Cost: $22
Explanation:
The equation is $154=7x because he spent a total of $154 on 7 tickets with the x representing the cost of each ticket.
To solve for x, you divide both sides by 7 to get x by itself. So 154/7 is 22, so each ticket is $22.
To check your work, you can multiply 7 by 22 and then multiply 7 by 25 to see which one equals $154
