The variable n can equal anything. You can use any variable to equal something. Variables are usually used in equations to represent some unknown quantity.
For example, a tutor wants to know how much he would get. If the hourly pay is $6, how much will he get for working for 3 hours?
So now, we have to use variables to represent how much the tutor will get.
So let's say, t is for total, h is for hours, and p = pay
It would look like this: t = hp
So you know what those represent, you'll plug in the numbers to find out how much he'll get.
t = 3(6)
t = $18
He'll get 18 dollars in 3 hours.
Hope this helps.
