Let's first find how many students bring their lunch to school. This is 30% of 300. To find this value, convert the percentage to a fraction (or decimal) and multiply:

Since 90 students bring their lunch to school, we can say 210 students do not bring their lunch to school. (300 - 90 = 210)
N+2 would be the correct answer... i think!!!!!!!!!!!!
Hope i helped!!!!!!!!
Plug it in your y= screen of your graphing calculator and hit 2nd and then graph. it will give u a table of values
Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.
