1. The problem states that 180 lunches were sold in total, and we need to find how many of these were salads. 2. From the pie chart description, salads represent about $\frac{3}{10}$ of the total lunches sold. 3. To find the number of salads sold, we use the formula: $$\text{Number of salads} = \text{Total lunches} \times \text{Fraction for salads}$$ 4. Substitute the values: $$\text{Number of salads} = 180 \times \frac{3}{10}$$ 5. Multiply: $$180 \times \frac{3}{10} = \frac{180 \times 3}{10} = \frac{540}{10}$$ 6. Simplify the fraction by canceling common factors: $$\frac{\cancel{540}^{54}0}{\cancel{10}^{1}0} = 54$$ 7. Therefore, the number of salads sold is 54. Final answer: **54 salads** were sold.
