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.

The function p(i)=15i−450p represents Vance's convention earnings as a function of items sold.

What is the practical domain of the function?
300≤i

all integers between 300 and 310 inclusive

[300,  310]

all real numbers

Answer 1

B i believe it issss.

Answer 2

The practical domain of the function is:

all integers between 300 and 310 inclusive

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.
