Question

Last year at a certain high school, there were 96 boys on the honor roll and 85 girls on the honor roll. This year, the number of boys on the honor roll increased by 25% and the number of girls on the honor roll increased by 20%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).

Answer 1

22.7

Explanation:

ok so, First we need to find new values:

96( 1 + 0.25) =120

85( 1+0.2)= 102

Boys last year girls last year total this year

96 85 181

Boys this year girls this year total this year

120 102 222

Find the overall increase:

181( 1+r)= 1.226519

THEN U SUBTRACT 1

r=0.226519

Multiply by 100 and round to nearest 10th

22.7%

Final Answer: 22.7%
