Answer:
D. $674.68
Step-by-step explanation:
We will use the well known equation for compound interest
Where
is the final total
is the principal amount (starting total)
is the interest rate as a decimal
is the number of times the interest is compounded each year
the number of years
Plugging in what we know from the question:
So the answer is D.
Hope this helps!
First off, you have to find a common denominator between 6 and 9 which is 18, so to rewrite your equation using the common denominators it would be 15/18+(-8/18)-(-36/18) when you combine these it equals (7/18)-(-36/18)=43/18
The problem is asking you to solve the equation
<em>y</em> = 12<em>x</em> + <em>n</em>
for the variable <em>n</em>. To do this, subtract 12<em>x</em> from both sides:
<em>y</em> - 12<em>x</em> = (12<em>x</em> + <em>n</em>) - 12<em>x</em>
<em>y</em> - 12<em>x</em> = <em>n</em>
