1. Glenn bought a car for 600,000 the yearly deprenation of his car is 10% of its value of the start of the year. What is the value of 5 years?

Answer:

The cars value after the 5-year depreciation is 393,660.

Step-by-step explanation:

Use geometric progression rule:

an = a₁ (r)ⁿ⁻¹

First year, a₁ = 600,000

n = 5

r = 1-0.1  or  0.9  ⇒  because of depreciation

Find the value of the car after its 5-year depreciation:

a₅ = 600,000 (0.9)⁵⁻¹

a₅ = 600,000 (0.9)⁴

a₅ = 600,000(0.6561)

a₅ = 393660
