Final answer:
The amount to be reported in the July income statement for salaries expense is $7,800.
Step-by-step explanation:
The amount to be reported in the July income statement for salaries expense is $7,800.
Since the employee's services were performed in July, the associated expense should be recorded in the same month's income statement. The fact that the payment will be made in the first week of August does not affect the timing of recognition for the expense. Therefore, the correct amount to report is the wages and salaries expense of $7,800.
