The number of trips that Hammerhead must sell to get break even is 200 trips.
Explanation:
Calculation of Break Even Point:
Break Even Point = Fixed Cost divided by Contribution Per Unit
The given data : Fixed Cost = $6,000
Contribution Per Unit = Selling Price minus Variable cost per unit
Thus, Contribution Per Unit = $50 - 20 = $30
Break Even Point = 6,000 / 30 = 200 trips
Thus, the number of trips that Hammerhead must sell to get break even is 200 trips.
