I am not sure what the question is here. I can tell you how to find the percent of kids that developed influenza in that class. We can compare it to the 20% of students nationwide. There could many different questions that stem from the piece of information you gave.
To find the percent of kids that developed influenza in that class do 6÷15 which gives you
.4 and written as a percent would be 40%.
Please message me if you have any questions! Hope this helps!
0.35 = 35/100.
Can be simplified. Divide by 5.
= 7/20
First combine like terms
3x - 7 - 2x + 5 = 6
x - 2 = 6
Get x by itself by adding 2 on both sides
x - 2 = 6
x = 8
Your answer is x = 8
4536000 elephants is the answer
