Answer:
D) $29,600
Explanation:
The mixed cost formula gives the relationship between the cost and the level of activities. It shows the cost as a function of the activity level.
The formula also shows that the cost is made up of a fixed element ($16,000) and a variable element ($3,40X).
Hence at an activity level of 4000 units,
Y = $16,000 + $3.40(4000)
= $29,600
