To find the percent decrease in earnings, we will use the formula for percentage decrease:

\[
\text{Percent Decrease} = \frac{\text{Original Amount} - \text{New Amount}}{\text{Original Amount}} \times 100
\]

### Given:
- **Original amount** (last month) = \$45
- **New amount** (this month) = \$30

Substitute these values into the formula:

\[
\text{Percent Decrease} = \frac{45 - 30}{45} \times 100 = \frac{15}{45} \times 100 = 0.3333 \times 100 = 33.33\%
\]

Thus, the percent decrease in Elle's earnings is **33.33%**.
