Answer: 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%
Answer:
Thats wrong
Step-by-step explanation:
Find new values:
150(1+0.24)=\color{green}{186}
150(1+0.24)=186
150(1+0.06)=\color{blue}{159}
150(1+0.06)=159
Last Year This Year
Boys 150 186
Girls 150 159
Total 300 345
\text{Find overall increase:}
Find overall increase:
300(1+r)=345
300(1+r)=345
\frac{300(1+r)}{300}=\frac{345}{300}
300
300(1+r)
​
=
300
345
​
1+r=1.15
1+r=1.15
r=0.15
r=0.15
Subtract 1
\text{Final Answer: }15\%
Final Answer: 15%
