Answer and Explanation:
The journal entry is shown below
Sales tax (($257,000 + $154,800) ×7%) $28,826
To sales tax payable $28,826
(Being the sales tax expense is recorded)
Here the sales tax is debited as it increased the expense and credited the sales tax payable as it also increased the liability
The calculation is as follows;
= $27,4990 ×100 ÷ 107
= $257,000
And,
= $165,636 × 100 ÷ 107
= $154,800
