The cost function can be written as C(x) = 0.6x + 800, where x is the number of hot dogs produced. 
To find the cost of producing 300 hot dogs, we can simply plug in x=300 into the cost function and evaluate: 
C(300) = 0.6(300) + 800 = 980
Therefore, the cost of producing 300 hot dogs is $980. 
Choice C is the only option that matches this answer.
