How much wood...? #3
Note: Reference to my two previous problems for additional information: #1 and #2
Now that our woodchuck is full and satisfied, he heads off to the city to get himself a mate. The survivors of his chucking spree, which includes 250 mature trees and 125 saplings, are overjoyed. Note that once a tree reaches its 1st birthday, it stops growing, and has a volume of 10,000 cubic feet. Each birthday of a tree results in the production of a sapling. 1 year after the woodchuck leaves the forest, how many trees, , and saplings (non-mature trees), , are there in the forest?

At the beginning of the problem, the trees are 1.5 years old and the saplings are .5 years old. After one year they will be 2.5 and 1.5 years old, respectively. In between at ages 2 and 1, both groups produce saplings. The 2 and 1 year-olds total 375 (250 trees and 125 former saplings), so each of their current saplings also total 375. So 3 7 5 3 7 5 is equal to 1 .
