Task Analysis

To solve this problem, we need to determine the number of adults in the theater given that there are children seated in 12 rows with 10 in each row, and the number of adults is three times less than the number of children.

Solution

Let's denote: - C as the number of children - A as the number of adults

Given: - Children are seated in 12 rows with 10 in each row. - The number of adults is three times less than the number of children.

We can express the number of adults in terms of the number of children using the given information.

Calculation

The number of adults can be expressed as: A = (1/3)C

Substitution

Substitute the value of C from the given information into the equation to find the number of adults.

Result

The number of adults in the theater can be calculated as follows: A = (1/3) * (12 * 10)

Final Calculation

A = 40

Therefore, there are 40 adults in the theater.
