Answer 1

To express the statement "Dale has three dollars more than twice the amount of money that Leo has" using variable expressions, we first define the variable:

Let \( d \) represent the amount of money that Leo has.

According to the problem, twice the amount of money Leo has can be expressed as \( 2d \).

Since Dale has three dollars more than this amount, we add 3 to \( 2d \). Therefore, Dale's amount can be expressed as:

\[
2d + 3
\]

So, the correct response is:

**If Leo has d dollars, then Dale has 2d + 3 dollars.**
