The gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.
We want to know how much percent of 'b' is 'a'.

Given that:
Here we assume that the term GMC is referring to gross margin cost.
Let this gross margin cost (GMC) $40 be P% of the original cost of the item $150.
Then, we get:
[tex]p = \dfrac{40}{150} \times 100 \approx 26.67 \text{(in percentage)}[/tex]
Thus, the gross margin cost for the case when the considered retailer’s gross margin on a $150 item is $40 is 26.67% approximately.
