Answer 1

Problem:

Laurie has to sell between 0 and 10 raffle tickets each week. The function R, where R(x) = 5.00x represents the amount of money Laurie sells raffle tickets. Which statement best represents the domain of the function for any given amount of raffle tickets.

Solution:

The graph of the function R(x) = 5x is:

Now the function that represents the real model (no negative number of rifles) would be:

Now, the domain of a function is formed by all the elements that have an image. Then, we can conclude that the correct answer is:

B. the set of all positive numbers.
