Answer:
$621
Step-by-step explanation:
-Profit is the net amount after deducting the total expenses from the sales revenue realized.
-Wally's expenses are:
[tex]E=100+200+500\\\\=800[/tex]
-Wally's sales revenue is:
[tex]R=sp\times w, sp-selling \ price, w= bushels\\\\=700\times 2.03\\\\=1421[/tex]
The profit made is therefore calculated as:
[tex]P=R-E\\\\=1421-800\\\\=621[/tex]
Hence, Wally's profit last year was $621
