I'm assuming that the pair of pants start out at a price of $7.50

First decrease by 10%

7.50 - 10% of 7.50 = 7.50 - 0.10*7.50

7.50 - 10% of 7.50 = 7.50 - 0.75

7.50 - 10% of 7.50 = 6.75

-------------------------------------------------------
Now increase by 10%

6.75 + 10% of 6.75 = 6.75 + 0.10*6.75

6.75 + 10% of 6.75 = 6.75 + 0.675

6.75 + 10% of 6.75 = 7.425

6.75 + 10% of 6.75 = 7.43

-------------------------------------------------------
To sum things up, you

Start with 7.50

Decrease 7.50 by 10% to get 6.75

Increase 6.75 by 10% to get 7.43

So the final price is $7.43
