Question: Question 9: Louis sees this special offer in a shop.
Louis buys both items.
How much does he pay?
Special Offer
iPad £489
Case £55
Buy both items and receive a 3% discount
1. **State the problem:** Louis wants to buy an iPad priced at £489 and a case priced at £55. There is a special offer giving a 3% discount if both items are bought together.
2. **Formula used:** To find the total price after discount, first find the total price without discount, then subtract the discount amount.
\[ \text{Total price before discount} = \text{Price of iPad} + \text{Price of Case} \]
\[ \text{Discount amount} = \text{Total price before discount} \times \frac{3}{100} \]
\[ \text{Total price after discount} = \text{Total price before discount} - \text{Discount amount} \]
3. **Calculate total price before discount:**
$$489 + 55 = 544$$
4. **Calculate discount amount:**
$$544 \times \frac{3}{100} = 544 \times 0.03 = 16.32$$
5. **Calculate total price after discount:**
$$544 - 16.32 = 527.68$$
6. **Final answer:** Louis pays $527.68$ after the 3% discount.
