Answer: If all conditions are met, all 3 discounts can be applied to the list price
Step-by-step explanation:
This is a series discount which means the following:
20 is for 20% off the list price which leaves 80%.
15 is for 15% off which leaves 85% and,
5 is for 5% off which leaves 95%.
If all conditions placed by the seller are met, all 3 discounts can be applied to the list price.
They are applied by multiplying the discounted price proportions.
= 0.8 * 0.85 * 0.95
= 0.646 will be the discounted price.
