There is 4.88% decrease in Olivia's score.

Step-by-step explanation:

Given,

Score on first math test = Old value = 82 points

Score on second math test = New value = 78 points

Change = New value - Old value

Change = 78 - 82 = -4

The negative sign indicates the decrease.

Decrease percent = \frac{Change}{Old\ value}*100

Decrease percent = \frac{4}{82}*100=\frac{400}{82}

Decrease percent = 4.88%

There is 4.88% decrease in Olivia's score.

Keywords: percentage, difference
