Final answer:
A price that is less than or equal to 70% of the sticker price indicates a 30% discount from the original price. It means the customer pays no more than 70% of the original price, making the corresponding answer a discount of 30%.
Step-by-step explanation:
When a price is described as being less than or equal to 70% of the sticker price, this indicates that a discount is being applied. Specifically, it means that no more than 70% of the original price is being charged. The remaining percentage, in this case, 30%, is the reduction from the original price. Therefore, the correct answer would be a) A discount of 30%.
Looking at this in terms of numerical examples, if an item originally costs $100, and it is now being offered at less than or equal to 70% of this original price, the new price would be $70 or less. The reduction in price from the original is 30% of $100, which is $30, hence this represents a 30% discount.
