To solve for how many donuts Deborah makes in 5 hours using a proportion, we can set up the following:
\[ \frac{33 \text{ donuts}}{7 \text{ hours}} = \frac{x \text{ donuts}}{5 \text{ hours}} \]
Now, we can complete the proportion:
\[ \frac{33}{7} = \frac{x}{5} \]
From here, to solve for \(x\), we can cross-multiply:
\[ 33 \cdot 5 = 7 \cdot x \]
This simplifies to:
\[ 165 = 7x \]
Now, divide both sides by 7:
\[ x = \frac{165}{7} \approx 23.57 \]
Since we are looking for whole donuts, Deborah would make approximately 23 whole donuts in 5 hours. The completed proportion is:
\[ \frac{33}{7} = \frac{x}{5} \]
