To find the sale price of an item that costs \( d \) dollars with a 30% discount, you would calculate 30% of \( d \) and then subtract that amount from the original price.

1. **Calculate the discount**: 30% of \( d \) is \( 0.3d \).
2. **Subtract the discount from the original price**: The sale price would be \( d - 0.3d \).

This simplifies to:

\[
d - 0.3d = 0.7d
\]

Thus, the correct expression to find the sale price is **0.7d**.

So the answer is **0.7 d**.
