Question

A city wants to plant maple and spruce trees to absorb carbon dioxide. It has $2100 to spend on planting spruce and maple trees. The city has 45000 ft^2 available for planting.
A. Use the data from the table. Write the constraints for the solution.
B. Write the objective function.
C. Graph the feasible region and find the vertices.
D. How many of each tree should the city plant to maximize carbon dioxide absorption?

Answer 1

data table looks like this:

spruce maple
planting cost $30 $40
area required 600 ft^2 900 ft^2
carbon diox.
absorption 650 lb/yr 300 lb/yr

Answer 2

its line equation, try to make the solution first.
30x+40y <=2100
600x+900y<=4500
absorbtion = 650x+300 y

Answer 3

so I should figure those 3 equations first? This whole thing has me so lost

Answer 4

my answer can answer A and B. C you have to draw those 2 function. after you draw you will find jog point.

Answer 5

for example you found that x=a, y=b, then the absorption is 650 a+300b

Answer 6

ok
