The following events took place at Tasty-Toppins Inc., a pizza shop that specializes in home delivery, during 2017:

a. January 1, purchased a truck for $16,000 and added a cab and an oven at a cost of $10,900. The truck is expected to last five years and be sold for $300 at the end of that time. The company uses straight-line depreciation for its trucks.

b. January 1, purchased equipment for $2,700 from a competitor who was retiring. The equipment is expected to last three years with zero salvage value. The company uses the double declining-balance method to depreciate its equipment.

c. April 1, sold a truck for $1,500. The truck had been purchased for $8,000 exactly five years earlier, had an expected salvage value of $1,000, and was depreciated over an eight-year life using the straight-line method.

d. July 1, purchased a $14,000 patent for a unique baking process to produce a new product. The patent is valid for 15 more years; however, the company expects to produce and market the product for only four years. The patent's value at the end of the four years will be zero.
