What algebraic expression relates the number of dimes to their total value?

The correct answer establishes a direct relationship between the number of dimes and their total value. Each dime is worth 10 cents, so to find the total value of a certain number of dimes, you multiply the number of dimes by 10. This relationship means that if you know how many dimes you have, you can easily calculate the total value in cents by applying that simple multiplication.

For example, if you have 5 dimes, the total value would be 5 multiplied by 10, resulting in 50 cents. This is a clear and straightforward way to express the relationship between quantity and value in this context.
