Chevrolet raised the base price of its volt by $1,200 to $32,500. what was the percent increase? (round to the nearest tenth percent.)

                                   _
The answer is 2608.3% increase (rounded is 2608.3% increase).

Explanation:

The formula for percent change is:

Percent change = (change/original) * 100

First, you must calculate the change:

32,500 - 1,200 = 31,300

Then, you must put it over the original (the original is 1,200):

Percent change = (31,300/1,200) * 100

Finally, compute the percent change with division and multiplication:
                                      _             _                        _
31,300/1,200 = 26.083   26.083 * 100 = 2608.3% increase

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
