Eli has 7 bottles of water. he will buy more bottles of water from the store. the store has 8 cases in stock and each case contains 24 bottles of water. the store will not sell partial cases. the function that models the number of bottles of water eli will have after his purchase is f(c)=24c+7, where c is the number of cases of water he buys.

the practical domain of the function is {}.

Eli has 7 bottles of water. He will buy more bottles of water from the store. The store has 8 cases in stock and each case contains 24 bottles of water. The store will not sell partial cases. The function that models the number of bottles of water Eli will have after his purchase is f(c)=24c+7, where c is the number of cases of water he buys.

The practical domain of the function is all positive integer because c represents the number of case, and there is no negative number of case and it is not sold in partial so only positive intger can satisfy the given function.
