The demand for books is: qd = 120 - p the supply of books is: qs = 5p 4) refer to scenario 2.1. what is the equilibrium price of books? a.5 b.15 c.20 d.10 e. none of the above

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
