To find the cost of the wings per wing, we can divide the total cost by the number of wings.
The total cost of the wings is $26.60 and the number of wings is 19.
We calculate the cost per wing as follows:
\[ \text{Cost per wing} = \frac{\text{Total cost}}{\text{Number of wings}} = \frac{26.60}{19} \]
Now, performing the division:
\[ \frac{26.60}{19} = 1.4 \]
Thus, the cost of the wings is $1.40 per wing.
