Final answer:
The variable cost for 4,400 units is $46,100.
This correct answer is 1)
Step-by-step explanation:
To calculate the variable cost for 4,400 units, we can use the total cost function y = 6,500 + 9X.
Plugging in X = 4,400, we get y = 6,500 + 9(4,400) = 6,500 + 39,600 = 46,100.
Therefore, the variable cost for 4,400 units is $46,100.
