The Cobb$-$Douglas production function is a classic model from economics used to model output as a function of capital and labor. It has the form

f$($L$,$ C$)=$ c$0$Lc$1$Cc$2$

where

c$0,$ c$1,$ and c$2$

are constants. The variable L represents the units of input of labor and the variable C represents the units of input of capital.

$($a$)$

In this example, assume

c$0=5,$ c$1=0\mathrm{.}25,$ and c$2=0\mathrm{.}75.$

Assume each unit of labor costs $$25$ and each unit of capital costs $$75.$ With $$90,000$ available in the budget, develop an optimization model for determining how the budgeted amount should be allocated between capital and labor in order to maximize output.
