To find out how much it costs to buy 10 dresses when 7 dresses cost £101.50, follow these steps:
1. Determine the cost of one dress:
- If 7 dresses cost £101.50, you can find the cost of one dress by dividing the total cost of the 7 dresses by the number of dresses.
- Cost per dress = Total cost of 7 dresses / Number of dresses
- Cost per dress = £101.50 / 7
- This gives a cost of £14.50 per dress.
2. Calculate the cost for 10 dresses:
- Now that we know one dress costs £14.50, we can find the total cost for 10 dresses by multiplying the cost of one dress by the number of dresses.
- Total cost for 10 dresses = Cost per dress × Number of dresses
- Total cost for 10 dresses = £14.50 × 10
- This gives a total cost of £145.00.
Therefore, it costs £145.00 to buy 10 dresses.
