Answer:
False
Total equivalent units    89,000 units
Explanation:
<em>Equivalent units are notional whole units which represent incomplete work and are used to apportion cost between work progress and completed work. These units are determined as follows:  </em>
Equivalent units = Degree of work done(%) × units of inventory 
Item                                          unit                                    Equivalent unit
Opening inventory            10,000    50% ×  10,000                 5000
Fully worked unit                  80,000     100%× 80,000              80,000
Closing inventory              20,000       20% × 20,000              <u>4,000</u>
Total equivalent units                                                              <u> 89,000</u>

<u>Notes:</u>
<em>1. Fully work represent units started and completed in the same period. They exclude the opening inventory.</em>
<em>Fully worked = 90000- 10,000 =80,000.</em>
<em>2. Note also at that the degree of completion</em> for opening inventory is the simply the balance of work remaining to be done.
<em>For example, for materials, 50% of work has been done on the opening inventory in the last period, hence the balance of 50% would be done this period
