Shya works part-time at a gift-wrapping. the store sells wrapping paper rolls and package of wrapping rolls. there are a total of 125 rolls and package. each roll costs $3.50 and each package costs $2.25. the total of all of the rolls and package is $347.50 . how many rolls of wrapping paper are there?

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.
