Answer
(a) cost per equivalent unit
Item Material Labour Overheads
Cost per EU($) 84.15 34.25 172.25
b) Total cost per equivalent = $290.65
Explanation:
<em>The weighted average method of valuation of work in progress does not separate opening work-in progress from the newly introduced. </em>
<em>The cost per equivalent units using this method is computed by dividing the total equivalent units by the cost element. This repeated for each of cost element categories.</em>
Item Material Labour Overheads
Opening WIP 36,900 61,650 299,715
Cost added <u>223,965</u> <u>41,100</u> 1<u>99,810</u>
Total cost($) a 260,865 102,750 499,525
Equivalent unit b 3,100 3,000 2,900
Cost per EU($) (a/b) 84.15 34.25 172.25
Total cost per equivalent unit = 84.15 + 34.25 + 172.25
Total cost per equivalent= $290.65
