Solution:
Given:

Using the simple interest formula,

Therefore, the simple interest is $960.
K is 23.
As for the equation, it is
29=k+6
To solve, subtract 6 from both sides.
The formula is
A=p e^rt
A future value 900
P present value 800
E constant
R interest rate 0.11
T time?
We need to solve for t
T=[log (A/p)÷log (e)]÷r
T=(log(900÷800)÷log(e))÷0.11
T=1.07 years round your answer to get 1 year
The answer is 6 because u have to divided it
