(2) Double-diminishing-balance method: Cullumber Arrow Ltd. purchased a new bus on October 1, 2024, at a total cost of \$159,585.

The new bus has an estimated residual value of $16,000, and an estimated useful life of either four years of 305.500km. Use of the bus will be sporadic so it could be much higher in some years than in others. Assume the new bus is driven as follows: 7,900 km in 2024; 100,400 km in 2025:64,500 km in 2026; 95.700 km in 2027; and 37,000 km in 2028. Cullumber Arrow has actober 31 year end.
