Answer and Explanation:
Computation:
Cost-to-cost method
Year Cost cost(%) Revenue Income
2016 $202,500 30% $270,000 $67,500
2017 $337,500 50% $450,000 $112,500
2018 $135,000 20% $180,000 $45,000
Total $675,000 100% $900,000 $225,000
Cost % = Cost of particular year / Total cost
Revenue:
Year 2016 =$900,000 × 30% = $270,000
Year 2017 = $900,000 × 50% = $450,000
Year 2018 = $900,000 × 20% = $180,000.
Income:
= Revenue - Cost
Year 2016 = $270,000 - $202,500
Year 2017 = $450,000 - $337,500
Year 2018 = $180,000 - $135,000
