Grady marks down some $2.59 pens to $2.09 for a week and then marks them back up to $2.59. 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.

Step-by-step explanation:

If there is zero before decimal ,

then it must have values.

Like,  200.4

Here, the zeros in one's and tenth places have values.

Now, for the zeros after decimal,

there are two cases-

If the zero is after decimal and there is no digit after this zero,

then this zero will not have any value.

like,  125.0

this zero have no value.

Now, if the zero is after decimal, but there are other digits after this zero,

then this zero must have value.

like, 125.03

this zero have value, since there is a digit 3 after the zero.
