In an effort to enhance waste management practices, a manufacturing company is exploring
resource allocation in various key areas. These areas include implementing quality control
measures and process optimization to reduce the production of defective products, redesigning
product packaging to minimize waste, and investing in recycling programs and equipment. The
manager estimates that by allocating RM x thousand to the quality control department, RM y
thousand for packaging redesign using eco-friendly materials, and RM z thousand for recycling
equipment, the monthly waste generation can be reduced to approximately W tonnes, where
(a)
16 13
W(x, y, z)=315-x 25 y 60 (21+3.65z +0.125z²).
Evaluate W. (30, 25, 15), W, (30, 25, 15), and W. (30, 25, 15). Then, interpret the
results in this context.

Expert Solution

Step 1: Write the given information:

The monthly waste generation can be reduced to approximately W tonnes.

$W open parentheses x space comma space y space comma space z close parentheses equals 315 minus x to the power of 16 over 25 end exponent y to the power of 13 over 60 end exponent open parentheses 21 plus 3.65 z plus 0.125 z squared close parentheses to the power of 1 divided by 5 end exponent$

To Find:

$W subscript x open parentheses 30 space comma space 25 space space comma space 15 close parentheses space comma space W subscript y open parentheses 30 space comma space 25 space space comma space 15 close parentheses space comma space W subscript z open parentheses 30 space comma space 25 space space comma space 15 close parentheses space comma space$
