Stomach with rugae
Rugae are sets of ridges formed by
folding of the wall of an organ. The stomach rugae exist in the mucosal and
submucosal layers of the stomach. They function through the action of
mechanoreceptors which provide contraction and allow the stomach to expand when
a bolus enters it. By this action, there is increase in the surface area of the
stomach for nutrient absorption during digestion.

= 200
The account receivable = $10,000 - $200
= $9,800
From the foregoing, it is obvious that the sale revenue would not be affected by this transaction. SO, the sale revenue = $10,000
