Sales: you can calculate this from the crop area, yield and selling price data for the 4 different crops. For example: for potatoes you have 25 ha * 10 tonnes/ha * $1000/tonne = $250,000
I assume that the variable cost figures are complete, and not in units of cost per tonne of cost per ha, but you'll have to verify that. For potatoes you have $300+ 150 + 250 + 4000 = $4700. Again, please verify that I interpreted your vc data correctly.
So add up all the sales revenue for all 4 crops, subtract the variable costs for all 4 crops, then subtract the fixed overhead, and you'll have your profit.
