Angie went to the store and bought two packs of cookies for a total of $15. Karen went to the store and bought 8 packs of the same cookies. How much did Karen spend?

2 packets of cookies = $15

1 packet of cookies = 15 ÷ 2

                                  = $ 7.5

8 packs of cookies = 7.5 × 8

                                 = $60

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.
