Answer:
A, D, E
Step-by-step explanation:
Universal Container can monitor how the discounts are affecting profitability by evaluating the difference between discounted and listed price. They can then reduce the discounts to increase profits if this is the reason for reduced profitability.
If this is not responsible for falling profits, it may be that too many products are available in a sales discounting opportunity. Universal Containers can remedy this by reducing the number of products included in an offer.
Their falling profitability can also be controlled by putting a management approval process in place, ensuring that the effects of a sales discounting plan on profitability are always considered.
