Answer: r= 1.22
Step-by-step explanation:
Formula for amount with simple interest =
, where
P= principal value , r= rate of interest , t = time.
Given: P= $2000, t= 5 years, r= 1.25% = 0.0125
Formula to compute compound amount :
When both have same worth then
taking log on both sides , we get
Hence, Value of r= 1.22
<h2>x = 9</h2><h3 />
<u>We know:</u>
- we can add/subtract the same expression to both sides of the equation to get an equivalent equation;
- we can multiply/divide both sides of the equation by the same non-zero number to get the equivalent equation.
<u>Equivalent equations</u> are algebraic equations that have identical solutions.
We have the equation:
<em>multiply bot sides by 3</em>
<em />
<em>divide both sides by 7</em>
