The total cost to plow a field consists of a fixed charge (\(F\)) and variable charge (\(V\)) that varies proportionally to the area of the field. What is the cost to plow a \(500\, \text{m}^2\) field?
(1) The total cost to plow a \(600\, \text{m}^2\) field is \(\$250\) more than the cost to plow a \(350 \, \text{m}^2\) field.
(2) The total cost to plow a \(400\, \text{m}^2\) field is \(\$400\) more than the fixed cost.
