1. **State the problem:** We need to find the discount percentage when the price of microscopes drops from 50 to 14. 2. **Formula:** The discount percentage is given by $$\text{Discount \%} = \frac{\text{Original Price} - \text{New Price}}{\text{Original Price}} \times 100\%$$ 3. **Calculate the discount amount:** $$50 - 14 = 36$$ 4. **Calculate the discount percentage:** $$\frac{36}{50} \times 100\% = \frac{\cancel{36}}{\cancel{50}} \times 100\% = 0.72 \times 100\% = 72\%$$ 5. **Answer:** The discount is 72%.
