Hey there! :)
6 = 1 - b
Like I mentioned in my previous answer, we must isolate our variable. In this case, our variable is b.
So, our first step is to subtract 1 from both sides.
6 - 1 = 1 - b - 1
Simplify.
5 = b
Therefore, b = 5
~hope I helped~
SOLUTION
Given the question in the question tab, the following are the solution steps to answer the question.
STEP 1: Write the formula for calculating compound amount

where
A = final compounded amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
STEP 2: Write the given data
Semiannually means that n will be 2

STEP 3: Calculate the compound amount

Hence, the compounded amount after 4 years is $18,748.1972
Answer: 115,340
