Final answer:
To represent the situation, use the equation 5x + 2y = 60. To solve for y, rearrange the equation y = (60 - 5x) / 2.
Step-by-step explanation:
To write an equation representing the given situation, we can use the formula:
5x + 2y = 60
Where 'x' represents the number of adult tickets and 'y' represents the number of children tickets. This equation represents the total amount spent on tickets. To solve for 'y', we can rearrange the equation:
y = (60 - 5x) / 2
