• Item – what is bought
• Price – how much it costs
• Payment – money given
• Change – money given back

1. Item: Biscuit, Price: ₦5, Payment: ₦10 Change = ₦10 – ₦5 = ₦___
2. Item: Pencil, Price: ₦20, Payment: ₦50 Change = ₦50 – ₦20 = ₦___
3. Item: Sweet, Price: ₦2, Payment: ₦5 Change = ₦5 – ₦2 = ₦___

Exercise 16: Shopping scenarios:

1. You want to buy a ruler for ₦15. You have ₦20. How much change will you get? Change = ₦___
