Answer:
let's say the item bought costs £20
sales tax first
20/100 X 7.5 = 1.50. 20 + 1.50 = 21.50
21.50/100 X 20 = 4.30
21.50 - 4.30 = £17.20
discount first
20/100 X 20 = 4
20 - 4 = 16
16/100 X 7.5 = 1.20
16 + 1.20 = £17.20
it wouldn't matter
No. Since there will be more of a fine, there will be more tax to take away. If the discount is taken first, then there will be less money to calculate the tax from. So tax before the discount would be worse, because it would cost more
