Volodomyr has a cell phone. he has a "pay as you go" plan that follows a linear relationship.

• two months ago, he paid $32 for 100 minutes of phone calls.
• last month, he paid $36 for 300 minutes of phone calls.

how much can he expect to pay this month if he used his phone for a total of 400 minutes?

38$

you just have to add and think about it as 30$ is the membership fee and for every 2$ you get 100 minutes

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.
