Donna is tasked with helping her supervisor decide which method to use when accounting for their company's by$-$product and two main products, all three of which result from a joint process. At the end of

the joint process, the by$-$product is worth $$1,000,$ Product T is worth $$8,040,$ and Product $W$ is worth $$12,060.$ The joint costs amount to $$4,600.$ Donna's company historically uses the sales value at split$-$

off method to allocate joint costs. If all of these products are sold by the end of the year, how much gross margin will Donna report for her company if she uses the production method to account for by$-$

products? $($Round proportion to $2$ decimal places, e$.$g$.0\mathrm{.}25$ and final answers to $0$ decimal places, e$.$g$.5,125.)$
