If 15 ceramic vases cost $25, and 5 glass vases cost $15, how much did I on average spend for each vase?

1.6$ (1.7$ rounded) for ceramic vases and 3$ for glass vases

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.
