N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.
Here's how to use n in an algebraic equation:
5 + n = 12
To find what N represents, let it be the only thing on the left side of the variable:
5 -5 + n = 12 - 5
n = 7

The answer is C. is right
Answer: 272 square feet
Step-by-step explanation:
We must find the total area of the backyard then subtract the area of the not allowed area from it. Clearly, the length and width of the backyard is 22 and 17ft respectively, so the total area is 22*17=374ft^2.
The restricted space can be seen as two rectangles, both with width 3 and length 17, making their area 2(17*3) =102
374-102= 272
Ok, so lets convert all the percents into decimals to help us solve this problem
A 3.0%= 0.03
B 3.5%= 0.035
C 4.0%= 0.04
D 4.5%= 0.045
Now, we can multiply $200 by all the decimals we just converted to see which one will add up to $208
200*0.03= 6-------200+6=206 (this is not equal to 208 so it's not A)
200*0.035=7--------200+7= 207 (Still does not equal 208, so it's not B)
200*0.04= 8---------200+8=208 C is your answer
