Last year at a certain high school, there were 125 boys on the honor roll and 100 girls on the honor roll. This year, the number of boys on the honor roll decreased by 8% and the number of girls on the honor roll decreased by 5%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary).

21.5%

Step-by-step explanation:

Step-by-step explanation: there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29

145-29=116

116 is this year number of boys on honor role

For girls.

=0.25*60=15

60-15=45

45 is this year number of girls on honor role.

Total number of students on honor role this year is 116+45 =161

Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100

= 0.215*100

= 21.5%
