Question: 35
A hospital coffee shop has monthly sales of $26,892. The coffee shop’s monthly
expenses are as follows: Cost of sales = $10,825 Salaries = $8,597 FICA = $2,150
Supplies = $1,975 Utilities = $2,345 What is the coffee shop’s profit margin for
the month?
A. 2%
B. 4%
C. 6%
D. 8%
Answer: B
The coffee shop’s profit margin for the month is 4%, as calculated below: Net
profit = monthly sales - (cost of sales + salaries + FICA + supplies + utilities) Net
profit = $26,892 - ($10,825 + $8,597 + $2,150 + $1,975 + $2,345) Net profit =
$1,000 Profit margin = net profit / sales Profit margin = $1,000 / $26,892 Profit
margin = 0.037 ˜ 0.04 = 4%

there is insufficient evidence to suggest that they are higher among pregnant

A. Promotes epithelial cell differentiation
B. Reduces the inflammatory response
