1) x = 5
2x + 5 = 30 - 3x
(+ 3x)
5x + 5 = 30
(- 5)
5x = 25
( / 5)
x = 5

2) x = -2
(-4 * 11x) + (-4 * 2) = 80
-44x - 8 = 80
(+ 8)
-44x = 88
( / -44)
x = -2

3) x = 49
3x + 33 = 180
(- 33)
3x = 147
( / 3)
x = 49

I hope this helps! The / symbol means divide by the way :)

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.

zzz [600]

Answer:

2.6667yd^3

Step-by-step explanation

Volume of the concrete = Length * width * height

Given

height = 6 inches

To yards;

1 in = 0.0277778yd

6 in = 6 * 0.0277778

6in = 0.1666668 yards

Width = 8 feet

Length = 6ft

LW = 48ft²

To yards;

1 ft = 0.333333yd

48 ft = 48(0.333333)

48 ft^ 2 = 15.999984yd^2

Volume = 15.999984 * 0.1666668

Volume = 2.6667 yd^3

Hence she will need 2.6667yd^3 concrete
