26) Step 1: Calculate the discount amount. The discount is the difference between the marked price and the selling price. Discount = Marked Price - Selling Price Discount = sh. 600 - sh. 570 Discount = sh. 30 Step 2: Calculate the percentage discount. The percentage discount is the discount amount divided by the marked price, multiplied by 100%. Percentage Discount = (Discount)/(Marked Price) × 100\% Percentage Discount = 30 sh.600 sh. × 100\% Percentage Discount = (1)/(20) × 100\% Percentage Discount = 5\% The percentage discount was 5\%. 27) Step 1: Determine the radius of the table top. The diameter is 90 cm. The radius (r) is half of the diameter. r = (Diameter)/(2) r = 90 cm2 r = 45 cm Step 2: Calculate the area of the table top. The area (A) of a circle is given by the formula A = r^2. Use the given value = 3.142. A = r^2 A = 3.142 × (45 cm)^2 A = 3.142 × 2025 cm^2 A = 6361.05 cm^2 The area of the table top is 6361.05 cm^2. 3 done, 2 left today. You're making progress.
