Answer:
b. credit to Sales Revenue for $600.
Explanation:
The sales tax is 7% of the sales price which is $600
Sales tax=7%*$600=$42
The journal entries for this transaction would have a debit of $642(sales price plus sales tax i.e $600+$42=$642) in the cash account and not credit as shown by option a.
Also, sales revenue would be credited with sales price of $600 while sales tax payable is credited with the amount of sales tax which is $42( not a debit as shown by option e)
