An anthropology article presents a hypothetical situation that could be described by a linear programming model. Suppose a popul

Answer:

The minimum labor = 270 hours and it is obtained when 0 units of plants and 18 animals are collected.

Step-by-step explanation:

We assume that x should represent the number of units of plants

Also y to represent the number of animals.

So, minimze (z) = 30 x + 15 y

Subject to:

30 x + 20 y ≥ 360

10 x + 25 y ≥ 300

y ≤ 8

0 ≤ x ≤ 25

0 ≤ y ≤ 25

Changing the above linear inequalities into linear equation; we have:

30 x + 20 y = 360

10 x + 25 y = 300

y = 8

The graph for the above discussion can be located in the attached diagrammatic expression below:

NOW, the corner points (0,18),(0,25),(25,25), and (25,8) can be calculated from the graph. From the diagram, the corner point $[\frac{60}{11} , \frac{108}{11} ]$ can be found by solving the system.

30 x + 20 y = 360

10 x + 25 y = 300

Corner point (10, 8) = 10 x + 25 y = 300

y = 8

Corner point Value of z = 30 x + 15 y

(0,18) 270

(0,25) 375

(25,25) 1125

(25,8) 870

$[\frac{60}{11} , \frac{108}{11} ]$ $\frac{3420}{11}$ ≅ 310.91

(10, 8) 420

∴

The minimum labor = 270 hours and it is obtained when 0 units of plants and 18 animals are collected.
