Answer:

x = 2 and x = -3

Step-by-step explanation:

We need to find the value of x in the below expression.

\sqrt{x+7} -1=x

Adding 1 to both sides,

\sqrt{x+7} -1+1=x+1\\\\\sqrt{x+7}=x+1

Squaring both sides,

x+7=(x+1)^2\\\\x+7=x^2+1+2x\\\\x^2+1+2x-x-7=0\\\\x^2+x-6=0\\\\x=2\ and\ -3

Hence, this is the required solution.

Olympia Hospital has overall variable costs of 25% of total revenue and fixed costs of $45 million
blagie [28]
  1. In terms of total revenue, the break-even point of Olympia Hospital is equal to $60 millions.
  2. The average daily revenue per patient-day that is necessary to achieve the break-even total revenue is $1,600.

<h3>What is the break-even analysis?</h3>

Break-even analysis is also referred to as cost-volume-profit analysis and it can be defined as a financial accounting technique that is used to determine the number of units (products) which a business firm must sell at a specific price, either on a monthly or annual basis, so as to cover all of its costs.

<h3>How to calculate the break-even point?</h3>

In terms of total revenue, the break-even point of Olympia Hospital can be calculated by using this formula:

Break-even point = Fixed cost/CM ratio

Break-even point = $45 million/(100% - 25%)

Break-even point = $45 million/75%

Break-even point = $45 million/0.75

Break-even point = $60 millions.

<h3>How to calculate the average daily revenue?</h3>

Average daily revenue = Break-even point/Number of patient-days

Average daily revenue = $60 millions/37,500

Average daily revenue = $1,600.
