Final answer:
To find the original price of the table, a proportion is set up with $284 being 71% of the original price. Solving the equation reveals that the regular price was approximately $400 before the discount.
Step-by-step explanation:
The correct answer is option C. To find the original price of the table, we need to set up a proportion where $284 is 71% of the original price. The original price can be represented by the variable x. Therefore, we set up the equation 0.71x = $284. To solve for x, we divide both sides of the equation by 0.71.
When we divide $284 by 0.71, we get approximately $400. This means that the regular price of the table was $400 before the discount was applied. Therefore, the table's price yesterday, before the sale, was $400.
This question involves calculating the original price of a table based on a discount percentage. We are given that the table is being sold today for $284, which is 71% of its regular price. To find the regular price, we can set up the equation: 0.71x = 284, where x is the regular price. To solve for x, we divide both sides of the equation by 0.71: x = 284 ÷ 0.71 = $400.
