1. **State the problem:** Mokaya bought and sold a cow twice at different prices. We need to find the total profit he made. 2. **Identify the transactions:** - First purchase price = 80000 - First selling price = 125000 - Second purchase price = 140000 - Second selling price = 155000 3. **Calculate profit for each transaction:** - Profit 1 = Selling price 1 - Purchase price 1 = $125000 - 80000 = 45000$ - Profit 2 = Selling price 2 - Purchase price 2 = $155000 - 140000 = 15000$ 4. **Calculate total profit:** - Total profit = Profit 1 + Profit 2 = $45000 + 15000 = 60000$ 5. **Conclusion:** Mokaya made a total profit of 60000 from the two transactions involving the cow.
