1. Problem: Find the original price if the discount is 8% and the discount amount is 55.60. Step 1: Let the original price be $x$. Step 2: Discount $= 8\%$ of $x = 0.08x$. Step 3: Given discount amount is 55.60, so $0.08x = 55.60$. Step 4: Solve for $x$: $$x = \frac{55.60}{0.08} = 695.$$ Answer: The original price is 695 (option B). 2. Problem: Find the sale price of a bag that costs 880 with a 10% discount. Step 1: Discount amount $= 10\%$ of 880 $= 0.10 \times 880 = 88$. Step 2: Sale price $= 880 - 88 = 792$. Answer: Sale price is 792 (option B). 3. Problem: Find the sale price if Alexis saved 194.85 which is 15% off from the original price. Step 1: Let original price be $x$.

Step 4: Solve for $x$: $$x = \frac{194.85}{0.15} = 1299.$$ Step 5: Sale price = Original price - discount = $1299 - 194.85 = 1104.15$. Answer: Sale price is 1104.15 (option C). 4. Problem: Find selling price if Collin wants 20% profit on a CP that costs 17990. Step 1: Profit = 20% of 17990 $= 0.20 \times 17990 = 3598$.
