What is the practical domain of the function

We are given function f(c) = 24c+5 that models the number of cans Luis will have after his purchase of more c number of cases Luis purchase.

We need to find the domain of the function in respect to the given function.

Here we used variable c. And c represents the  number of cases Luis can purchase.

Minimum number of cases Luis can purchase = 0.

There are total 12 cases in stock.

Therefore, maximum number of cases Luis can purchase = 12.

then
