Let original price be "x":
After reduction: 0.95x
------
Solve:
k(0.95x) = x
0.95k = 1
k = 1/0.95 = 1.0526
-------
Ans: Increase price by 5.26%

Hey,
So to solve this problem, we need to think of the price as a value, like x. So if the original price was x, then when the company reduced the price by 5%, the equation would look like this:
x - (x)(5%) => x-.05x => x(1-.05) => x(.95)
Now, if we want to get back to the original price, we need to get .95x back to 1x. So the difference between 1 and .95 is .05 which translates to 5%. So the retailed must increase the new price by 5% to sell the article at the old price.
I hope this helps!
