On January 1 of the current year, Jambon purchased equipment for use in developing a new product. Jambon uses the straight-line depreciation method. The equipment could provide benefits over a 10-year period. However, the new product development is expected to take five years, and the equipment can be used only for this project. Jambon's current year expense equals:

1. The total cost of the equipment.
2. One-fifth of the cost of the equipment.
3. One-tenth of the cost of the equipment.
4. Zero.
