Answer:
Step-by-step explanation:
For showing the comparative income statement, first we have to do the calculations which are shown below:
For 2020 = Pretax income using weightage average pricing - tax rate @30%
= $201,100 - $60,330
= $140,770
For 2019 = Pretax income using weightage average pricing- tax rate @30%
= $147,000 - $44,100
= $102,900
For 2018 = Pretax income using weightage average pricing - tax rate @30%
= $175,200 - $52,560
= $122,640
We ignored the computation through FIFO method
