Jabari owns 100 shares of stock a and 45 shares of stock b. for the past month, his stocks have been fluctuating inversely each week. stock a decreased by m cents per share. which equation can be used to find the total change in value of his shares?
a. v=(100*-m) + (45*n)
b. v=(100*m) + (45*-n)
c. v=100(4*-m)+ 45(4*n)
d. v=145(-m*n)

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.
