First, let's calculate the decrease in each product:
[tex]\begin{gathered} suit\text{ 1}:\\ \\ 695-445=250\\ \\ \\ \\ suit\text{ 2}:\\ \\ 550-287=263 \end{gathered}[/tex]Now, let's calculate the absolute markdown:
[tex]38\cdot250+20\cdot263=14760[/tex]Then, dividing this amount by the sales for December, we have:
[tex]\frac{14760}{60000}=0.246=24.6\%[/tex]Therefore the correct option is A.
