Problema Solution
Three types of trees are in a local park. The number of aspens is 4 more than twice as many oaks, and 50 more maples than oaks. There are a total of 874 trees in the park. How many of each kind are there?
Answer provided by our tutors
let
x = the number of aspens
y = the number of oaks
z = the number of maples
The number of aspens is 4 more than twice as many oaks:
x = 4 + 2y
and 50 more maples than oaks:
z = 50 + y
There are a total of 874 trees in the park:
x + y + z = 874
by solving the system of equations:
x = 4 + 2y
z = 50 + y
x + y + z = 874
we find:
x = 414 aspens
y = 205 oaks
z = 255 maples
