solution: To find the profit, we want to find out how much the math club earned from selling the various baked goods and subtract the cost of producing those goods, $\$15$, from the number we get.
  
  First let's calculate how much the math club earned from selling cookies. The cookies were sold at a price of three for $\$1$, so the math club earned $54\div 3\cdot\$1=18\cdot\$1=\$18$ from selling cookies.
  
  Next, let's calculate how much the club earned from selling cupcakes. At a price of $\$2$ each, the club earned $20\cdot \$2=\$40$ from selling cupcakes.
  
  Finally, let's calculate how much the club earned from selling brownies. At a price of $\$1$ each, the club earned $35\cdot\$1=\$35$ from selling brownies.
  
  Now let's add up these numbers to find out how much the club earned in total and subtract $\$15$ from that number to find the club's profit. We obtain \begin{align*}
  \$18+\$40+\$35-\$15&=\$18+\$40+\$35-\$15\\
  &=\$18+\$40+\$35+(-\$15)\\
  &=\$18+\$40+(\$35+(-\$15))\\
  &=\$18+\$40+(\$20)\\
  &=\boxed{78}.
  \end{align*}Notice how we used the definition of subtraction, $a-b=a+(-b)$ to $\$35-\$15$ as $\$35+(-\$15)$ and the associative property of addition to group the numbers together.
