Initial number of grams of air freshener = 25 grams.
We need to take final quantity by Q, number of days after start t.
Let us write equations:
(a) The decrease is 4 grams per day.
Q = Intial quantity - 4 × number of days.
Q = 25 - 4t.
(b) The decrease is 9% per day.
9% could be written in decimals as 0.09.
(c) The decrease is at a continuous rate of 12% per day.
We need apply formula of continuous exponential function for continuous decrease.
Therefore,
