🏪 Market Story
It's back-to-school time! Amina's mother gives her ₦1,000 to buy supplies for herself and her younger brother. Here are the prices:
- Exercise books: ₦35 each
- Pens: ₦20 each
- Pencils: ₦10 each
- Erasers: ₦5 each
- School bag: ₦250 each
- Ruler: ₦15 each
Each child needs: 4 exercise books, 2 pens, 3 pencils, 1 eraser, and 1 ruler. Can they afford it?
📝 Let's Learn
Cost per child:
- Exercise books: 4 × ₦35 = ₦140
- Pens: 2 × ₦20 = ₦40
- Pencils: 3 × ₦10 = ₦30
- Eraser: 1 × ₦5 = ₦5
- Ruler: 1 × ₦15 = ₦15
Total per child: ₦140 + ₦40 + ₦30 + ₦5 + ₦15 = ₦230.
For 2 children: 2 × ₦230 = ₦460.
Money left: ₦1,000 − ₦460 = ₦540. They have enough for the supplies and still have money for other things!
✏️ Practice Questions
- Can Amina also buy a school bag (₦250) for each child with the remaining ₦540? How much would 2 bags cost?
- After supplies and bags, how much money would be left?
- If Amina's mother gives only ₦700, can she buy supplies for both children (₦460) and one school bag (₦250)?
Click to see answers
- 2 × ₦250 = ₦500. Yes, ₦540 is enough for 2 bags (₦500).
- ₦540 − ₦500 = ₦40 left.
- ₦460 + ₦250 = ₦710. ₦700 < ₦710. No, she's ₦10 short.
💡 Remember
Big shopping trips need all four operations: multiply for quantities, add for totals, subtract to check your budget, and divide to split costs. Plan before you spend!
