Answer:Accounting rate of return = 15%
Step-by-step explanation:
Accounting rate of return =Net income(Net cash flow - depreciation expense) / Average investment x 100
but depreciation = Cost of equipment - salvage value/ useful life
=(144,000 - 4000)/ 4= 140,000/ 4= $35,000
also,
Average Investment = Cost of equipment +salvage value /2
=( 144,000+4000)/ 2= 148,000 /2 = $74,000
Accounting rate of return =Net income(Net cash flow - depreciation expense) / Average investment x 100
(46,100 - 35,000)/ 74,000} x 100 =11,100/74,000=0.15 x 100= 15%
