Answer and Explanation:
The computation of the adjusted amount of the last three days of the accounting period is shown below:
Since for five days work week, the total wages is $2,400
So per day it would be
= $2,400 ÷ 5 days
= $480
Now for 3 days, it would be
= $480 × 3 days
= $1,440
Now the adjusting entry is
Salaries and wages expense Dr $1,440
To Salaries and wages payable $1,440
(Being the salaries are adjusted)
