Let's use the variable 'x' to represent the original bill amount.
According to the given information, Stan took Lily to his friend's restaurant on a date. Stan wanted to remove the $12 dessert from the bill. So, the remaining bill amount, after removing the dessert, will be (x - 12).
The equation to determine the amount of the original bill, b, would then be:
(x - 12) + 0.2x = b
Simplifying this equation, we have:
1.2x - 12 = b
