Grady marks down some $4.59 pens to $4.09 for a week and then marks them back up to $4.59. find the percent of increase and the percent of decrease to the nearest tenth. are the percents of change the same for both price changes? if not, which is a greater change? complete the explanation, and round your percents to the nearest tenth.

Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)

Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

Step-by-step explanation:

$4.59 has been changed to $4.09.

Percent change = [(Value after  - Value before) / Value before]*100

                          =%

                          =%

                          =%

                           =% ( Rounded to nearest tenth)

Percentage decrease is 0.1% ( Rounded to nearest tenth)

Now lets calculate the percentage change from $3.59 to $4.09.

Percent change = [(Value after  - Value before) / Value before]*100

                          =%

                          =%

                          =%

                           =% ( Rounded to nearest tenth)

Percentage increase is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

the answer would be  

a.

3: 1
