Answer:Price of the table yesterday is x.
Price of the table today is $513.
$513 is 76% of yesterday's price x. 76% can be also written down as 76 divided by 100 (percentage) or 76/100 = 0.76.
Formula we can set up now is: x= 513 / 0.76 (To get the price of yersterday's table we need to divide the price of today's table with percentage in decimal form).
x= 675
The price of yesterday's table was $675 since 76% of that price (675 times 0.76) equals 513 dollars.
