This is hard to solve when we don't know the visual graph this question is trying to refer from
30% is 3/10. 260 times 3/10 is 780/10, or 78. She read 78 pages. 260 - 78 is 182 pages left.
To find the density of racon all you have to do is to divide number of racoons with surface area because as name says you need to get x number of racoons per m^2
its own name tells you what you need to divide with what.
answer is:
20/10 = 2 raccoons per m^2
