Question

Taila earns d dollars per week. How much does Taila earn in 10 weeks?

Answer 1

The answer is 10d (10 times d)

Answer 2

`10d` dollars

Explanation:

`d` is a variable, which is just a placeholder for an unknown value. Therefore, we can treat
`d` as if it's a number.

If you earn a certain amount of dollars per week, and you work for 10 weeks, then to find how much money you earn, you'd multiply the amount of weeks (10) by the dollars per week right?

Same logic applies for variables.

Since we have
`d` acting as a placeholder for the amount earned per week, then the total amount of money earned in 10 weeks is
`10\cdot d`, which can just be represented as
`10d`.

Hope this helped!
