A company manufactures a certain product. The total cost of production consists of a fixed setup cost and a variable cost per unit produced. Last month, it cost the company $1200 to produce 100 units. This month, it cost the company $2100 to produce 250 units. Which of the following systems of linear equations represents this situation, if represents the fixed setup cost, in dollars, and represents the variable cost per unit, in dollars?
F + 100V = 2100
F + 250V = 1200
100F + V = 1200
250F + V = 2100
F + 100V = 1200
F + 250V = 2100
100F + 1200V = 1
250F + 2100V = 1
