1. **State the problem:** An item originally priced at 35 is on sale for 45% of the original price. We need to find the sale price. 2. **Formula used:** Sale price = Original price \times Percentage of original price (in decimal form). 3. **Convert percentage to decimal:** 45% = \frac{45}{100} = 0.45. 4. **Calculate sale price:** $$\text{Sale price} = 35 \times 0.45$$ 5. **Perform multiplication:** $$35 \times 0.45 = 15.75$$ 6. **Interpretation:** The sale price is 15.75. **Final answer:** The item costs 15.75 on sale.
