The movie house gives away a $5 coupon for every 4 movies purchased. how many movies would you have to purchase in all before receiving both a coupon and bag of popcorn at the same purchase?

5 movies because for 4 movies equals a coupon

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.
