Last year at a certain high school, there were 150 boys on the honor roll and 150 girls on the honor roll. This year, the number of boys on the honor roll increased by 24%
and the number of girls on the honor roll increased by 10%. By what percentage did
the total number of students on the honor roll increase? Round your answer to the
nearest tenth (if necessary).

17%

Step-by-step explanation:

Last year:

Number of boys = 150 boys

Number or girls = 150 girls.

Total = 300 students

This year:

Number of boys = 150 + (24% × 150)

= 150 + (0.24 × 150)

= 150 + 36

= 186

Number or girls = 150 + (10% × 150)

= 150 + (0.1 × 150)

= 150 + 15

= 165

Total students = 186 + 165 = 351

Percentage increase = (351 - 300) / 300 × 100

= 51 / 300 × 100

= 17%

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

m
