It is given that the price of the carpet is $ 28.99 per square yard
Step 1: Convert square yard to square meter
1 square yard = 0.836 square meter
Step 2: Calculate the cost/square meter
Now based on the relation in step (1) we can write
0.836 square meter of carpet costs $ 28.99
Therefore the cost of 1 square meter of the carpet would be
= $ 28.99 * 1 sq meter/0.836 sq meter
= $ 34.68
