Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of bushels of peanuts = 800
Price of each bushels of peanuts = $5.85
And there is mark up rate = 33%
So, Total price would be
[tex]1.33\times 800\times 5.85\\\\=\$6224.4[/tex]
If there is spoilage rate = 21%
So, the remaining rate would be 1-0.21=0.79
so, Number of remaining bushels of peanuts would be
[tex]0.79\times 800\\\\=632[/tex]
So, Selling price per bushel would be
[tex]\dfrac{622.4}{632}\\\\=\$9.85[/tex]
Hence, Option 'c' is correct.
