Kathryn has a recipe that needs teaspoon
of butter for every 2 cups of milk. If Kathryn
increases the amount of milk to 4 cups, how
many teaspoons of butter are needed?

2 teaspoons of butter

We know that the number has increased to 4 cups of milk, which is double the original amount, so we just double the teaspoons of butter needed as well.

Cups of milk:

4

Teaspoons of butter:

2

step-by-step explanation:

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.
