Final answer:
The solution to the equation given is to isolate 'r' by dividing both sides by 20000 and then subtracting 1 from the result. 'r' is found to be 1.7, which, when converted to a percent, becomes 170%.
Step-by-step explanation:
To solve the equation: 54000=20000(1+r), you want to find the value of 'r'. First, divide both sides by 20000 to get 54000 / 20000 = 1 + r, which simplifies to 2.7 = 1 + r. Then, subtract 1 from both sides to get r = 1.7 or 170%. The question suggests a possible error in that it asks for (x−max=1), which does not seem directly related to the given equation. Instead, to find 'r', we take the next steps:
-
- Divide 54000 by 20000 to get 2.7.
-
- Subtract 1 from 2.7 to isolate 'r' on one side of the equation.
-
- 'r' is then 1.7, which is the rate as a decimal.
To convert to a percent, multiply the decimal by 100. Therefore, r = 1.7 x 100% = 170%.
When you are asked to round to three decimal places, it is typically in the context of a more precise decimal. However, here r is already a simple decimal that does not require rounding.
