Answer:


\text{\$}$219.27$

Step-by-step explanation:

We were given that:

Pamela bought an electric drill at 85% off the original price (she bought it at 15% of the original price)

She paid $32.89 for the drill

The regular price is calculated using simple proportion as shown below:


\begin{gathered} 15\text{\%}=\text{\$}32.89 \\ 100\text{\%}=\text{\$}x \\ \text{Cross multiply, we have:} \\ x\cdot15\text{\%}=\text{\$}32.89\cdot100\text{\%} \\ x=\frac{\text{\$}32.89\cdot100\text{\%}}{15\text{\%}} \\ x=\text{\$}219.27 \\ \\ \therefore x=\text{\$}219.27 \end{gathered}

Therefore, the regular price was $219.27
