Final answer:
The original price of the table yesterday was $450, calculated by dividing the sale price of $279 by 62%.
Step-by-step explanation:
If today's sale price of the table is $279 and this price is 62% of its regular price, then to find the original price of the table, you can set up the equation:
0.62 × (original price) = $279
To find the original price, divide $279 by 0.62:
Original price = $279 / 0.62
Original price = $450
Thus, the original price of the table yesterday was $450.
