1. **Problem 11: Calculate the discount period for a note.** The note is dated June 6 and discounted on October 8. The note term is 200 days. 2. **Step 1: Calculate the number of days from June 6 to October 8.** - June 6 to June 30: $30 - 6 = 24$ days - July: 31 days - August: 31 days - September: 30 days - October 1 to October 8: 8 days Total days elapsed = $24 + 31 + 31 + 30 + 8 = 124$ days 3. **Step 2: Calculate the discount period.** Discount period = Total note term - days elapsed $$\text{Discount period} = 200 - 124 = 76$$ days 4. **Answer for Question 11:** 76 days (Option 1) 5. **Problem 12: Calculate the selling price with a 70% markup on selling price.** Given cost price $C = 66$, markup rate $m = 70\% = 0.7$ on selling price $S$. 6. **Step 1: Use the formula for markup on selling price:** $$C = S - m \times S = S(1 - m)$$ 7. **Step 2: Solve for $S$:** $$S = \frac{C}{1 - m} = \frac{66}{1 - 0.7} = \frac{66}{0.3}$$ 8. **Step 3: Simplify:** $$S = 220$$ 9. **Answer for Question 12:** The Winners' Circle should sell the glove for 220
