The publisher of a newsletter determines that with either a $10 or a $90 monthly subscription fee, the publisher will break even each month (profit=$0). Which of the following functions could model the publisher’s monthly profit P(x), in thousands of dollars, where x is the monthly subscription fee, in dollars?

Answer 1

The function that could model the publisher's monthly profit P(x) is:

P(x) = -10 + x

This function represents the monthly profit for each subscriber, where x is the monthly subscription fee. When x = $10, the profit will break even at $0.
