Sal has £7.50. He wants to buy one soap and one body cream. Does he have enough money to also buy one lip scrub? Show working to support your answer.
How to approach this question
1. Find the prices of soap, body cream, and lip scrub from the list.
2. Add these three prices together to find the total cost.
3. Compare the total cost with the amount of money Sal has (£7.50).
4. Conclude whether he has enough money or not.
Full Answer
First, we need to find the total cost of the items Sal wants to buy: one soap, one body cream, and one lip scrub.
From the price list:
- Soap: £2.00
- Body cream: £3.80
- Lip scrub: £1.75
Total cost = £2.00 + £3.80 + £1.75 = £7.55
Now, we compare the total cost to the money Sal has.
Sal has £7.50.
The total cost is £7.55.
Since £7.55 is greater than £7.50, Sal does not have enough money. He is short by 5p.
Common mistakes
✗ Adding the prices incorrectly.
✗ Only adding two of the items.
✗ Making the wrong conclusion based on the calculation (e.g., calculating £7.55 and saying "Yes").
