The Row $-$ On $-$ Wave Company $($ROW$)$ produces a line of non$-$motorized boats. ROW uses

a normal$-$costing system and allocates manufacturing overhead using direct manufacturing

labor cost. The following data are for $2020$ :

Requirement $2.$ Compute the amount of under$-$ or overallocated manufacturing overhead.

Identify the formula and calculate the under$-$ or manufacturing overallocated overhead. $($Use parentheses or a minus sign to report overhead overallocated.$)$

Requirement $3.$ Calculate the ending balances in work in process, finished goods and cost of goods sold if under$-$ or overallocated manufacturing overhead is as follows: $($a$)$ written off to cost of

goods sold, $($b$)$ prorated based on ending balances $($before proration$)$ in each of the three accounts, $($c$)$ prorated based on the overhead allocated in $2020$ in the ending balances $($before proration$)$

in each of the three accounts.
