b=3
I found this out by subtracting and adding on both sides.
The thousandths place is the 3rd digit after the decimal.
So:
47,268.56<u>8</u>593 = 47,268.569
The 3rd option is your answer
Answer:
The correct answer is $8532.17
Step-by-step explanation:
The formula for calculating investments with compound interests is as follows:

Where:
R is the annual interest rate,
t is the number of times the investment is to be compounded in a year,
n is the number of years,
P is the principal amount invested.
Replacing in the formula with the given values you have:

X + x + 165 = 1315
2x + 165 = 1315
subtract 165 from both sides
2x = 1150
divide both sides by 2
x = 575
January 575
February 575 + 165 = 740
So for this you will be doing proportions. Your equation will look like this: 
Firstly, cross multiply: 
Next, square root both sides of the equation, and your answer should be
