A business' profit margin is the ratio between the gross profit and net sales. It's ideal for a business to have a profit margin closest to 1. For the given situation, Sally has a gross profit of $32, 508.63 and a profit margin of 68% or 0.68. Thus, we have
[tex] 0.68 = \frac{32508.63}{sales} [/tex]
[tex] sales = \frac{32508.63}{0.68} = 47806.81 [/tex]
Therefore, the net sales earned by Sally's hair salon is $47, 806.81.
Answer: D. $ 47, 806.81
