Final answer:
The amount reported in the July income statement for supplies expense is $880.
Step-by-step explanation:
The amount reported in the July income statement for supplies expense is $880.
Supplies on hand at the end of the month are valued at $520. We can calculate the amount of supplies used during the month by finding the difference between the initial supplies balance ($1,400) and the supplies on hand at the end of the month ($520):
Supplies used = Initial supplies balance - Supplies on hand at end
Supplies used = $1,400 - $520 = $880
