At the beginning of last year (2021), Richter Condos installed a mechanized elevator for its tenants. The owner of the company, Ron Richter, recently returned from an industry equipment exhibition where he watched a computerized elevator demonstrated. He was impressed with the elevator's speed, comfort of ride, and cost efficiency. Upon returning from the exhibition, he asked his purchasing agent to collect price and operating cost data on the new elevator. In addition, he asked the companys accountant to provide him with cost data on the companys elevator. This information is presented here.

		Old Elevator			New Elevator
Purchase price		$104,000			$161,000
Estimated salvage value		0			0
Estimated useful life		5 years			4 years
Depreciation method		Straight-line			Straight-line
Annual operating costs
other than depreciation:
Variable		$35,200			$9,000
Fixed		22,300			8,500

Annual revenues are $240,000, and selling and administrative expenses are $29,000, regardless of which elevator is used. If the old elevator is replaced now, at the beginning of 2022, Richter Condos will be able to sell it for $25,500.

a. (I already solved this part, I got $57,000 which was a loss of sales)

b.

Prepare a 4-year summarized income statement for each of the following assumptions: (1) The old elevator is retained.

				Retain Old Elevator
Revenues				$enter a dollar amount
Less costs:
Variable costs		$enter a dollar amount
Fixed costs		enter a dollar amount
Selling & administrative		enter a dollar amount
Depreciation		enter a dollar amount		enter a subtotal of the previous four amounts
Net income				$enter a net income or loss amount in dollar

(2) The old elevator is replaced.

				Replace Old Elevator
Revenues				$enter a dollar amount
Less costs:
Variable costs		$enter a dollar amount
Fixed costs		enter a dollar amount
Selling & administrative		enter a dollar amount
Depreciation		enter a dollar amount		enter a subtotal of the previous four amounts
Operating income				enter operating income amount in dollar
Less: Loss on old elevator				enter Loss on old elevator in dollars
Net income				$enter a net income or loss amount

c. Using incremental analysis, determine if the old elevator should be replaced. (In the first two columns, enter costs and expenses as positive amounts, and any amounts received as negative amounts. In the third column, enter net income increases as positive amounts and decreases as negative amounts. Enter negative amounts using either a negative sign preceding the number e.g. -15 or parentheses e.g. (15).)

		Retain Old Elevator		Replace Old Elevator		Net Income Increase (Decrease)
Variable operating costs		$enter a dollar amount		$enter a dollar amount		$enter a dollar amount
Fixed operating costs		enter a dollar amount		enter a dollar amount		enter a dollar amount
New elevator cost		enter a dollar amount		enter a dollar amount		enter a dollar amount
Salvage on old elevator		enter a dollar amount		enter a dollar amount		enter a dollar amount
Totals		$enter a total dollar amount		$enter a total dollar amount		$enter a total dollar amount

should the elevator be replaced? Yes or no?
