A park ranger spent $208 to buy 12 trees.
Redwood trees cost $24 each and
spruce trees cost $16 each. How many of
each tree did the park ranger buy?

Let x represent number of redwood trees and y represent number of spruce trees.

We have been given that a park ranger bought 12 trees. We can represent this information in an equation as:

We are also told that redwood trees cost $24 each, so cost of x redwood trees would be .

Each spruce tree costs $16, so cost of y spruce trees would be .

Since the park ranger spent $208 on trees, so we can represent this information in an equation as:

Upon substituting equation (1) in equation (2), we will get:

Therefore, the park ranger bought 2 redwood trees.

Upon substituting in equation (1), we will get:

Therefore, the park ranger bought 10 spruce trees.
