Based on the given information, we can observe that the profit Kate earns is increasing by $6 for every 3 additional brownies sold. Therefore, we can determine that Kate earns $6 for every 3 brownies sold.

To find the profit for a certain number of brownies sold, we can use the following equation:

Profit = ($6 / 3) * (Number of brownies sold - 1)

Using this equation, we can calculate the profit for other numbers of brownies sold:

For 1 brownie sold:
Profit = ($6 / 3) * (1 - 1) = $0

For 16 brownies sold:
Profit = ($6 / 3) * (16 - 1) = $30
