Step-by-step explanation:
To calculate the percent decrease in the number of games won by Jaheim's favorite basketball team from last year to this year, we use the formula for percent change:
Percent Decrease = ((Old Value - New Value) / Old Value) x 100
Substituting the given values:
Percent Decrease = ((13 - 8) / 13) x 100
Percent Decrease = (5 / 13) x 100
Percent Decrease = 0.3846 x 100
Percent Decrease = 38.46%
Rounded to the nearest hundredth, the percent decrease is 38.46%.
