Answer:
The number of years needed is 15.75 years.
Step-by-step explanation:
The investment amount (present value) = $200
Interest rate =4.5%
Double of investment = $400
Now we have to find the time or number of years in which the investment amount will be doubled. So, just use the below formula to find the number of years.
Future value = present value ×(1+interest rate)^n
400 = 200×(1+4.5%)^n
N = 15.75 years
The number of years required to double the amount is 15.75 years.
Answer: Move terms to the left side−52+3=−9−5x2+3x=−9−52+3−(−9)=0−
Common factor−52+3+9=0−5x2+3x+9=0−(52−3−9)=0
Divide both sides by the same factor−(52−3−9)=0−(5x2−3x−9)=052−3−9=0

Step-by-step explanation:
The amount of sales before growth according to the article is $153.85 million
<h3>How to find sales before growth?</h3>
let
- Sales before growth = x
- Percentage growth = 30%
- New sales = $200 million
200 = x + (30% × x)
200 = x + (0.3 × x)
200 = x + 0.3x
200 = 1.3x
x = 200/1.3
x = 153.846153846153
Approximately,
x = $153.85 million
