There was 55.3% decrease in the number of points scored by football team.

Step-by-step explanation:

Given,

Points scored in first game = Old value = 38 points

Points scored in next game = New value = 17 points

Change = New value - Old value

Change = 17 - 38 = -21

The negative sign indicated decrease in points.

Percent decrease = [tex]\frac{Change}{Old\ value}*100[/tex]

Percent decrease = [tex]\frac{21}{38}*100[/tex]

Percent decrease = [tex]\frac{2100}{38}[/tex]

Percent decrease = 55.26%

Rounding to nearest tenth

Percent decrease = 55.3%

There was 55.3% decrease in the number of points scored by football team.
