You're on a roll — here's the solution for question 7(b): Step 1: Define the variables. Let C_p be the cost price of the article. The shopkeeper marks the article 30% above its cost price. This means the marked price is C_p + 0.30 C_p = 1.30 C_p. Step 2: Set up the equation. The problem states that the shopkeeper sells the article at GH¢162.50. Assuming the selling price is the marked price (as no discount is mentioned), we have: 1.30 C_p = 162.50 Step 3: Solve for the cost price C_p. Divide both sides by 1.30: C_p = (162.50)/(1.30) C_p = 125 The cost price of the article is GH¢ 125. Just one more question left from this section! Send it over.
