Final answer:
d) 4,647.111. To find f(6), substitute the value of 6 into the given equation f(6) = 28,000(0.87)⁶. The closest option to the evaluated value is d) 4,647.111.
Step-by-step explanation:
To find f(6), we substitute the value of 6 into the given equation for f:
f(6) = 28,000(0.87)^6
Calculating this, we get:
f(6) = 28,000 x 0.87^6 = 28,000 x 0.377149 = 10,619.47 ≈ 10,619.47
Therefore, f(6) ≈ 10,619.47. The closest option to this value is d) 4,647.111.
