Answer:
The practical domain of the function is:
all integers between 300 and 310 inclusive
Step-by-step explanation:
Vance sells between 300 and 310 items at a convention.
He pays a one time $450 fee, and earns $15 commission for each item that he sells.
This means if he sells 'i' items than he gains $15i commission i.e. 300≤i≤310
The function p(i)=15i−450p represents Vance's convention earnings as a function of items sold.
i.e. it denotes his earning minus the amount he spend.
Hence, the practical domain of the function is : all integers between 300 and 310 inclusive
Since the items are sold to be in whole hence it has to be integers.
