Suppose a tractor purchased at a price of $60,000 is to be depreciated by the double declining-balance method over a 10-year period. It can be shown that the rate at which the book value will be decreasing is given by
R(t) = 13988.61e−0.22614t (0 ≤ t ≤ 10)
dollars/year at year t. Find the amount by which the book value of the tractor will depreciate over the first 7 years of its life. (Round your answer to the nearest dollar.)

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.
