Washington, West Virginia, Wisconsin, Wyoming
Four states out of 50
4 / 50 * 100 = 8 per cent.
It's 300 because you divide 60 by 12 which gives you 5, then multiply 60 and 5.
IF A MOD DOESN'T DELETE THIS
8 is the GCF, so that means it's 8(3+5) = 8(8) = 64
First multiply 0.8 times m, then multiply 0.8 times -5.
This will give you 0.8m-4 = 10
Then add four to both sides to get you 0.8m =14.
Divide both sides by 0.8 to get m=17.5
Hope this helped. Good luck! :)
