Read a photographed receipt

Image input
Typed numbers
depends_on

Task

From a photo of a restaurant receipt, read the first item, how many items there are, the subtotal, discount and total, and whether it was paid in cash; then work out the discount as a percentage of the subtotal.

Challenges

The only input is a photo of a crumpled receipt: there is no text to copy from.
Amounts are printed as 194,000. Each must come back as the number 194000, not a string, and not 194.
The discount percentage is not printed anywhere. It has to be worked out from the subtotal and the discount, so it is asked after them with depends_on.
