Answer

Explanation:

Step1: Calculate total number of pairs

Since 1 dozen = 12, 7 dozen pairs is $7\times12 = 84$ pairs.

Step2: Calculate correct unit - price

The total cost is $94.08$. The unit price $u$ is calculated by dividing the total cost by the total number of pairs. So $u=\frac{94.08}{84}=1.12$.

Step3: Analyze the error

The contractor likely divided the total cost by 7 instead of $7\times12$. $94.08\div7 = 13.44$.

Answer:

$1.12$
