1. Paquito estimated the scrap value of a computer shop 20 years after
purchase. He senses that the best depreciation method to use is the
declining-balance method, but he doesn’t know what depreciation rate to
use. He observes that the purchase price of the computer shop was ₱ 245
000 three years ago, and an estimate of its current salvage value is ₱ 180
000. What is a good estimate of the value of the computer shop after 20
years?
