Hu... How can you be increasing and decreasing? Someone explain this to me lol. After a price reduction of x%, an item has its price increased to its original value. What was the percent of increase? Express your answer as a common fraction in terms of x.

The percent of increase is x/100

Step-by-step explanation:

Let us have the original price as $100

So, what this mean is that to be at this price, the price was formerly at 100 + x%

Mathematically, the price before reduction will be;

100 + x/100

So, we want to calculate the percentage increase

Mathematically, that will be the marked up price minus the original divided by the original * 100%

We have this as;

((100 + x/100) - 100))/100 * 100%

= x/100/100 * 100%

= x/10,000 * 100

= 100x/10,000

= x/100

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
