Answer Interest rate = 12.3%
The compound interest formula is given by:
Where
A = Future amount
P = Present amount (Principal amount)
r = Interest rate in decimal form
n = No. of times compounded per year
t = time in years.
We can say that if:
Present amount = P
Future amount = 3P
r = 12.3/100 = 0.123
n = 1
t = ?
Substitute the values in the formula of compound interest:
Taking log on both sides.
Round off to nearest option
t ≅ 9 years

Answer:
-$11,000 is the economic profit or we can say it is a loss.
Step-by-step explanation:
The job paid Bob = $100000
The insurance cost is = $8,000
The material cost is = $15,000
The lease payments are = $8,000
The sales revenue is $120,000.
So, Bob's economic profit is: 
Therefore, his economic profit is -$11000.

General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.8x = 7.2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 0.8: x = 9
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 0.8(9) = 7.2
- Multiply: 7.2 = 7.2
7.2 does indeed equal 7.2. ∴ x = 9 is a solution.
And we have our final answer!
