Multiplying with Naira: Bus Fare for a Family

🎯 What You'll Learn

You will use multiplication to calculate costs for families and groups, like bus fares and meal costs.

🏪 Market Story

Tunde's family of 5 is taking a bus from Ikeja to Lekki. The bus fare is ₦150 per person. How much will the family pay altogether? 5 × ₦150. Let's work it out: 5 × 100 = 500, 5 × 50 = 250. Total: 500 + 250 = ₦750.

📝 Let's Learn

Multiplication helps you calculate costs for groups of people. The formula is: Total cost = Number of people × Cost per person.

Example 1: Bus fare is ₦100 per person. A family of 4: 4 × ₦100 = ₦400.

Example 2: Lunch costs ₦200 per person. For 3 friends: 3 × ₦200 = ₦600.

Example 3: A keke ride costs ₦50 per person. 3 passengers: 3 × ₦50 = ₦150.

Tip: For big numbers, partition! 3 × ₦250 = 3 × 200 + 3 × 50 = 600 + 150 = ₦750.

✏️ Practice Questions

1. A danfo ride costs ₦80 per person. How much does it cost for 4 people?

Click to see answers

1. 4 × ₦80 = ₦320. (4 × 8 = 32, add zero = 320.)
2. 6 × ₦150 = 6 × 100 + 6 × 50 = 600 + 300 = ₦900.
3. 5 × ₦120 = 5 × 100 + 5 × 20 = 500 + 100 = ₦600.

💡 Remember

Whenever everyone pays the same amount, multiply to find the total. Number of people × cost per person = total cost. This works for bus fares, meals, tickets, and more!
