We then subtract the cost of goods sold ($126,520 m) from total revenues ($144,077 m) to obtain a gross profit of $17,577 m. To obtain the gross profit margin, we divide the gross profit ($17,577 m) by total revenues ($144,077) for a margin of 12.20%.
Outer ear. The outer ear is the external portion of the ear, which consists of the auricle (also pinna) and the ear canal. It gathers sound energy and focuses it on the eardrum (tympanic membrane). Contents.
The outer ear is called the pinna, or the auricle. The human outer ear is not designed as efficiently as the ears of most other animals, so humans do not hear as well. In humans, the auricle is rather rudimentary, attached flat against the side of the head and connected by small ligaments and muscles.
