Lolonyo Company is contemplating the purchase of a new high-speed widget grinder to replace the existing grinder. The new grinder costs GHs 105,000 and requires GHs 5,000 in installation costs; it has a 5-year usable life and would be depreciated under MACRS using a 5-year recovery period. The cost of the existing machine was 70,000 and it was being depreciated under the 5-year recovery period. The existing machine has been in use for the past 3 years and Lolonyo can currently sell the existing grinder for GHs 7,000 without incurring any removal or clean-up costs. To support the increased business resulting from purchase of the new grinder, accounts receivable would increase by GHs 40,000, inventories by GHs 30,000, and accounts payable by GHs 58,000. At the end of 5 years the new grinder would be sold to net GHs 29,000 before taxes. The firm is subject to a 40% tax rate. The estimated earnings before depreciation, interest, and taxes over the 5 years for both the new and the existing grinder are shown in the following table.

Year	New Grinder (GHS)	Existing Grinder (GHS)
1	83,000	23,000
2	93,000	23,000
3	73,000	23,000
4	63,000	23,000
5	53,000	23,000
