<em>To solve for a variable, you just need to isolate the variable to one side.</em>
<h3>7.</h3>
For this, just divide both sides by r and <u>your answer will be 
</u>
<h3>8.</h3>
For this, divide both sides by nR and <u>your answer will be 
</u>
<h3>9.</h3>
Firstly, multiply both sides by T: 
Next, subtract FV on both sides of the equation: 
Lastly, multiply both sides by -1, and <u>your answer will be 
</u>
<h3>10.</h3>
Firstly, multiply both sides by 1000: 
Lastly, divide both sides by tc and <u>your answer will be 
</u>
Say you're trying to figure out what percentage 3 is of 15.
3/15 = x/100
You would cross multiply so..
3(100) = 15x
Then simplify.
300 = 15x
300/15 = 15x/15
20 = x
Therefore, 3 is 20% of 15.
Well, you earn 14x dollars per month, where x is the number of hours you work every month. All you need to do is multiply 14 times the number of hours you work every month.

Answer:
Margin of Error = 1.96 
7.75 = 15.19
Step-by-step explanation:
i) Margin of Error of a population with a standard deviation of 7.75?
ii) Let us assume a two tailed test with a 95% confidence interval
iii) 
iv) therefore Margin of Error = 1.96 7.75 = 15.19
Hey there!
First, you would multiply 125*135%= 168.75
Then you would add 125 to 168.75 and you would get 293.75.
Next, you would multiply 293.75*7.5%= 22.03
Finally, add 22.03 to 293.75 and your answer is...
$315.78
