Final answer:
To find the percentage mark-up, you calculate the increase in price as a percentage of the cost price. The calculation for this specific case yields a 24% mark-up, making the correct answer c) 24%.
Step-by-step explanation:
To find the percentage mark-up, you need to calculate the increase in price as a percentage of the cost price. The formula for percentage mark-up is:
Percentage Mark-Up = ((Selling Price - Cost Price) / Cost Price) x 100%
Let's calculate the mark-up for this case:
- Cost Price (C) = £3500
- Selling Price (S) = £4340
- Mark-Up (M) = S - C = £4340 - £3500 = £840
- Percentage Mark-Up = (M / C) x 100% = (£840 / £3500) x 100%
After doing the calculation:
Percentage Mark-Up = (840 / 3500) x 100% = 24%
Therefore, the correct answer is c) 24%.
