the number of the children ticket purchased was one less than ten times the number of adults tickets purchased

To solve this problem, we need to set up an equation using the given information.

Let's say the number of adult tickets purchased is represented by the variable "A," and the number of children tickets purchased is represented by the variable "C."

According to the information given, the number of children tickets purchased was one less than ten times the number of adult tickets purchased. We can express this as:

C = 10A - 1

In this equation, "10A" represents ten times the number of adult tickets purchased, and "-1" represents one less. By substituting the value of "10A - 1" into the variable "C," we can determine the number of children tickets purchased.

Now, if you have the exact number of adult tickets purchased, you can substitute that value into the equation and solve for the number of children tickets. And if you have the number of children tickets purchased, you can substitute that value into the equation and solve for the number of adult tickets.
