Here is the formula you'll need
Total = Principal * (1 + (rate/n))^n*years
I don't know how to solve that for "n" so we'll use trial and error.
If compounded annually, total =
<span>
<span>
<span>
10,841.24
</span>
</span>
</span>
If compounded quarterly, total =
<span>
<span>
<span>
10,955.64
</span>
</span></span><span>If compounded monthly, total =
</span>
<span>
<span>
<span>
10,981.82
</span>
</span>
</span>
If compounded daily, total =
<span>
<span>
<span>
10,994.58
</span>
</span>
</span>
Therefore the answer is "A", daily.

540 seconds which is equal to 9 minutes.
Answer:
y= 1 and X=4
Step-by-step explanation:
8x +7y =39
8x +2y =34
elimination method(we multiply 8x+7y=39 or 8x + 2y= 34 by -1 to eliminate 8x)
lets multiply 8x+7y = 39 by - 1
-8x -7y = -39
8x +2y = 34
(8x-8x)+(2y-7y)= (-39+34)
0 + (-5y) = -5
-5y= -5......dividing both sides by -5
<em> y = 1</em>
8x +2y =34....... substituting y by 1
8x +2(1)= 34
8x + 2= 34
8x = 34-2
8x = 32.....dividing both sides by 8
<em>x = 4</em>
Lets check;
8x +2y = 34
8(4) +2(1) = 34
32 + 2 =34
<em>34 = 34</em>
8x + 7y = 39
8(4) + 7(1) = 39
32 + 7 =39
<em>39 = 39</em>
Before you do the steps, change the fractions given to improper fractions:
2 2/3 = 8/3
3 1/6 = 19/6
Now, I think the first step they want you to write is:
8/3 (divided by) 19/6
When you divide two fractions, it's the same as multiplying the first fraction by the reciprocal of the second fraction. (A reciprocal is a fancy way of saying you flip the fraction)
So the next step will look like this:
8/3 x 6/19
With this setup, you can cross simplify the fractions so that they look like this:
8/1 x 2/19
When you multiply this, you get 16/19
Let me know if you have any questions!
