Do you pay $3.694 a gallon of gasoline this is 90% of the price of a gallon of gasoline one year ago what was the price of a gallon of gasoline one year ago

Price of gallon of gasoline one year ago is $ 4.1

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.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
