PRCTCHG2

- Finds the resulting number, when an initial value is increased or decreased by a certain percent.

Useful for:

- SAT
- ACT
- Algebra 1

Solution:

Run PRCTCHG2 (how?) and enter the following values, pressing ENTER after each one: (Note that the percent change is -30, not 30, because we want to *decrease* the price by 30%.)

Type 1 and press ENTER, since there is only one percent change in this problem.

The program reports:

Interpretation: **The sale price is $35.**

Note: If the problem requires more than one percent change, choose 2 in the previous screen and enter the next percent increase or decrease.
