Answer:
Approximately 23%
Step-by-step explanation:
we know that
The high school graduating class of 2010 was 260 people
5 years later the high school graduating class was 320 people
In this problem
260 people represent the 100%
so
using proportion
Find out what percentage represent the difference (320-260)=60 people
Let
x -----> the percentage
25% means 0.25 (It also means 1/4.)
50% means 0.5 (It also means 1/2.)
0.25 of 30.44 = 7.61
0.5 of 13.50 = 6.75
From 7.61, subtract 6.75.
OK. I did it. The question just says "do it". It doesn't ask us what the result is.
If anybody asks you, you can do the subtraction, or just tell them it's 0.86 .
