Year Weighted-Average FIFO 2018 $370,000 $395,000 2019 390,000 430,000 2020 410,000 450,000 Instructions a. What is Mattke’s net income in 2020? Assume a 20% tax rate in all years. b.

b)     $52,000

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

 Weighted average  FIFO    Difference    [email protected]%(difference)  net effect

2018  370,000               395,000    25,000                     5,000           20,000
