To find out how much Jamie saves, we need to calculate the total discounts applied to the hardcover fiction book priced at $32.99.
1. **Calculate the sale price with the 20% off:**
\[
\text{Discount} = 32.99 \times 0.20 = 6.598
\]
\[
\text{Sale Price} = 32.99 - 6.598 = 26.392
\]
2. **Now apply the 15% coupon on the sale price ($26.39):**
\[
\text{Coupon Discount} = 26.392 \times 0.15 = 3.9588
\]
\[
\text{Final Price} = 26.392 - 3.9588 = 22.4332
\]
3. **Calculate total savings:**
\[
\text{Total Savings} = 32.99 - 22.4332 = 10.5568
\]
Rounded to two decimal places, the total savings is approximately **$10.56**.
Therefore, the answer is:
**a. $10.56**.
