In early January 2015, NewTech purchases computer equipment for $146,000 to use in operating activities for the next four years. It estimates the equipments salvage value at $30,000.

Prepare a table showing depreciation and book value for each of the four years assuming straight-line depreciation.

i have the following

cost minus salvage=116000

estimated useful life(years)=4

annual depreciation expense= 29,000

2015-2018 annual depreciation = 29000

i am missin the year end book value for the following years 2015-2018

i am not sure how to calculate it.
