Answer:
B) Increase the unit contribution margin by decreasing the MTBF
Explanation:
Since Beetle is already competitive in terms of awareness and price, it would be unnecessary to decrease the price or increase awareness, as it could even result in a financial loss.
By decreasing the MTBF (mean time between failures), the company's operations become a lot more efficient. That results in the faster coverage of fixed costs.
The unit contribution margin shows us the share of the product unit price that is aimed to cover fixed costs (it is not consumed by variable costs). Therefore, decreasing the MTBF would improve the unit contribution margin and thus propel a more efficient operating system, where more products will be produced and more profit will be generated with each item sold.
