Answer: 20% discount.
Step-by-step explanation:
We need to set up a proportion to figure out how much percent discount they have.
We can do that by taking the price the customer pays and dividing that by the original price.
So, 246.4/308.
This gives us .8 or 80%, but that is not the answer.
They are paying 80% meaning to find the discount we would subtract 80% from 100% and get 20%.
