How do you write a numerical or variable expression for each quantity: the value in cents if 7nickels?
We're being asked to write an expression that expresses the value, in cents, of seven nickels.
First we need to know the value of a nickel. It's 5 cents. So let's write that as:
#7N=(7)(5) cents.
And we can simplify it to:
To write a variable expression for this (which would tell us how to calculate how many cents an unknown number of nickels would be), we would write it like this:

The numerical expression for the value in cents if 7 nickels is (7 \times 5 = 35) cents. The variable expression would be (5n), where (n) represents the number of nickels. Therefore, for 7 nickels, the expression would be (5 \times 7 = 35) cents.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
