$15.12

Step-by-step explanation:

You just need to find 84% of 18 which is 15.12. what you do is you convert the percent into 0.84 and multiply is by the original price which is 18.

84%=0.84

0.84 times 18 = 15.12

:)

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.
