Suggestion for more ticket types

Hi,

I have one suggestion:

When we put the option of different prices, selection appears in the value of discount or accretion in%, but the value appears qualto is already applied this percentage, for example:

normal value $ 200
for students (20%)
...

My idea is that the value has to appear with the discount, eg

normal value $ 200
Student $ 160 (-20%)
...
So the folks who sign up for selection in addition to knowing the percentage discount also sees the value

another detail, the percentage appear decimal numbers that can confuse the user

for example, in the case of a 40% discount for students, appears:

for students (- 40.00%)

would be better:

for students (-40%)

In complete suggestion, for example, would look like this:

Normal $ 200,00
for students $ 160,00 (-40%)

Somehow I have already implement this improvement?
