If the price of a textbook is $40 before tax is added on, and tax is 10%, what will the final price of the textbook be?

The dress's price is $40. That is 100% of the dress's price. Since tax is 20%, you need to add 20% to the 100%. The total cost including tax will be 120% of the cost of the dress.Jan 15, 2019

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.
