On March 31, 2021, Susquehanna Insurance purchased an office building for $13,500,000. Based on their relative fair values, one-third of the purchase price was allocated to the land and two-thirds to the building. Furniture and fixtures were purchased separately from office equipment on the same date for $1,250,000 and $750,000, respectively. The company uses the straight-line method to depreciate its buildings and the double-declining-balance method to depreciate all other depreciable assets. The estimated useful lives and residual values of these assets are as follows: Service Life Residual Value Building 30 5% of cost Furniture and fixtures 20 5% of cost Office equipment 10 $35,000 Required: Calculate depreciation for 2021 and 2022. (Do not round intermediate calculations.)

Areal estate agent is considering changing her cell phone plan. there are three plans to choose from, all of which involve a monthly service charge of $20. plan a has a cost of $.42 a minute for daytime calls and $.17 a minute for evening calls. plan b has a charge of $.52 a minute for daytime calls and $.15 a minute for evening calls. plan c has a flat rate of $80 with 275 minutes of calls allowed per month and a charge of $.38 per minute beyond that, day or evening.a. determine the total charge under each plan for this case: 150 minutes of day calls and 70 minutes of evening calls in a month. (do not round intermediate calculations. round your answer to 2 decimal places. omit the "$" sign in your response.)c. if the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal? (round each answer to the nearest whole number.include the indifference point itself in each answer.)d. suppose that the agent expects both daytime and evening calls. at what point (i.e., percentage of total call minutes used for daytime calls) would she be indifferent between plans a and b?
