From the image, we see that the purchases made at Electronic Warehouse include the following items and prices:

- HP Touch-Screen Laptop: $349.52
- Blue-Ray Disc: $19.99
- Asus Chromebook: $129.00
- SanDisk Flash Drive: $11.49

The subtotal for these purchases is $510.00, and the sales tax rate is given as 8%. To calculate the sales tax, we need to multiply the subtotal by the sales tax rate.

Sales tax = Subtotal × Sales tax rate  
Sales tax = $510.00 × 0.08 = $40.80

Thus, the amount of sales tax on the purchases is **$40.80**.
