Kryger [21]

The percent of change in the number of points she scored between the first and second tests  = 4.878 %

<h3>What is percentage decrease?</h3>

If the data is decreasing,

Decrease = Original Number - New Number.

Then: divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100.

Given that:

The score of first Math test = 82

The score of second Math test = 78

Changes occurs in marks by=78-82

                                               =-4

So, there is decrease in marks.

We have to find the decrease percentage:

Decrease%= \frac{change \;in \;value}{Original\; value} *100

                   = \frac{4}{82} *100

                   = 0.04878 * 100

                  = 4.878 %

There is 4.88% decrease in Olivia's score.
