1. **State the problem:** The original price of the shirt is 27. It is reduced by 15% in a sale. We need to find the new price after the reduction. 2. **Formula used:** To find the new price after a percentage reduction, use: $$\text{New Price} = \text{Original Price} \times (1 - \frac{\text{Percentage Reduction}}{100})$$ 3. **Apply the values:** $$\text{New Price} = 27 \times (1 - \frac{15}{100})$$ 4. **Simplify the fraction:** $$\text{New Price} = 27 \times (1 - 0.15)$$ 5. **Calculate inside the parentheses:** $$\text{New Price} = 27 \times 0.85$$ 6. **Multiply to find the new price:** $$\text{New Price} = 22.95$$ **Final answer:** The new price of the shirt after a 15% reduction is 22.95.
