Answer 2

Suppose you're at the beach, and the rental charge for snorkeling gear is 12 dollars per hour.
Let C stand for the total cost of renting snorkeling gear.
The amount you'll pay for using the gear depends on the amount of time you have it.

Number of hours_____Rental charge
1___________________$12 X 1 = $12
2___________________$12 X 2 = $24
3___________________$12 X 3 = $36
4___________________$12 X 4 = $48

The rental charge follows this pattern:

Rental charge = $12 X number of hours
____________ = $12 X t
$$\huge C=12t$$
The letter t stands for the hours shown in the table : 1, 2, 3, or 4.
Also, t can stand for other hours not in the table. We call t a "variable."

A "variable" is a symbol used to represent one or more numbers.
