how would I solve this?

On January 1. Simply Good Eatery purchased a new oven at a cost of $36,000. The restaurant estimates that the oven will last about 8 years and have a residual value of $4,000. Assuming that Simply Good Eatery uses the straight-line depreciation method, what is the oven's book value at the end of year 37 $36.000 $20.000 $24,000 $32.000 $28.000
