c) Net Income                             360,000            344,000        316,000

Explanation:

Part 1) Determine the net income for 2020 as follows using the First In First Out (FIFO)

= FIFO 2020 = $450,000 - The Income Tax

= $450,000 - ($450,000 x 0.35)

= $450,000- $90,000

= $360,000

Part 2) Compute the cumulative effect in change of the weighted average to FIFO
