Answer:

Step-by-step explanation:
![\left[\begin{array}{ccc}-&2018&2019\\Beg.Inv&21,000&29,350\\Purchase&151,500&187,500\\Available&172,500&216,850\\End.Inv&32,500&35,500\\COGS&140,000&184,500\\Adj.End.Inv&-3,150&6,250\\Real COGS&143,150&178,250\\Real End-Inv&29,350&41,750\\\end{array}\right]](https://img.qammunity.org/2020/formulas/business/college/rpppyz243qc45kkdp9ljvz9scs4lq9fizx.png)
When overstated, it means an inventory with a book value of 100 is really 95
When understated, it means an inventory with a book value of 100 is really 105
This makes the COGS lower than it should in the first case
and higher than it should in the second
Notice:
Because of 2018 adjustment, beginning and availalbe good must be recalculate for 2019
