1. **State the problem:** We need to find the final price of a sno-cone machine originally priced at 139 after applying a 20% discount and then adding a 6.75% sales tax. 2. **Formula and rules:** - Discounted price = Original price \times (1 - Discount rate) - Final price after tax = Discounted price \times (1 + Tax rate) 3. **Calculate the discounted price:** $$\text{Discounted price} = 139 \times (1 - 0.20) = 139 \times 0.80 = 111.2$$ 4. **Calculate the final price after tax:** $$\text{Final price} = 111.2 \times (1 + 0.0675) = 111.2 \times 1.0675$$ 5. **Perform the multiplication:** $$111.2 \times 1.0675 = 118.66$$ 6. **Interpretation:** The final price of the sno-cone machine after the discount and sales tax is approximately $118.65. **Answer:** D 118.65
