Questions: It costs £87.50 to buy 7 coats. How much does it cost to buy 10 coats? Give your answer in pounds (£).

Solution Steps

To find the cost of 10 coats, first determine the cost of one coat by dividing the total cost of 7 coats by 7. Then, multiply the cost of one coat by 10 to find the total cost for 10 coats.

To find the cost of one coat, divide the total cost of 7 coats by the number of coats:

\[ \text{Cost per coat} = \frac{87.50}{7} = 12.50 \]

Multiply the cost of one coat by 10 to find the total cost for 10 coats:

\[ \text{Cost for 10 coats} = 12.50 \times 10 = 125.0 \]
