Your answer is D.
________________

Company will reduce the fuel use by 10% each year.
100% - 10% = 90%
So it will use 90% of what it had used previous year.

the company used 20,000 gallons of fuel in the year prior to starting the program.

Next year, it will use = 20000× 90/100 = 20000 × 0.9

in 2nd year, it will use = (20000×0.9) × 0.9 = 20000 × 0.9^2

in 3rd year, it will use = (20000× 0.9^2) × 0.9 = 20000 × 0.9^3

See the pattern.

Fuel to be used in nth year = 20000 × 0.9^n

So f(n) = 20000× 0.9^n = 20000(0.9)^n
