Step-by-step explanation:
Given,
Increased price of plane ticket = $616
Increase percent = 12%
Let,
x be the original price of ticket.
Now,
The original price is 100% and 12% is increased, therefore;
New price = (100+12)% = 112%
Thus;
$616 is 112% of x.
112% of x = 616

Dividing both sides by 1.12

The cost before increase was $550.
