You can put this solution on YOUR website! There are 850 Douglas fir and ponderosa pine trees in a section of forest bought by Sawz Logging Co. The company paid an average of $300 for each Douglas fir and $225 for each ponderosa pine. If the company paid $217,500 for the trees, how many of each kind did the company buy?
x = number of Douglas fir trees
850 – x = number of Ponderosa pine trees
300x + 225(850 - x) = 217,500
300x + 191,250 - 225x = 217,500
75x + 191,250 = 217,500
- 191,250 - 191,250
____________________________
75x = 26,250 divide by 75
___divide
75x
x = 350 Douglas fir trees
850 – x = 500 Ponderosa Pine trees
