To find out how much Jerry pays for 19 dozen pencils, we can first calculate the total cost before any discounts are applied, and then apply the discount if applicable.
1. **Calculate the cost before the discount**:
- The price of one dozen pencils is $1.10.
- For 19 dozen, the total cost is:
\[
19 \times 1.10 = 20.90 \, \text{dollars}
\]
2. **Check if the discount applies**:
- The discount of 1.5% applies to purchases of more than 12 dozen.
- Since Jerry is purchasing 19 dozen, he qualifies for the discount.
3. **Calculate the discount amount**:
- First, we need to find 1.5% of the total cost:
\[
\text{Discount} = 0.015 \times 20.90 = 0.3135 \, \text{dollars}
\]
4. **Subtract the discount from the total cost**:
- The final cost after applying the discount is:
\[
20.90 - 0.3135 = 20.5865 \, \text{dollars}
\]
5. **Round to the nearest cent**:
- Rounding $20.5865 to the nearest cent gives us:
\[
\text{Total cost} = 20.59 \, \text{dollars}
\]
Therefore, Jerry pays **$20.59** for 19 dozen pencils.
