Answer 2

" 18% off means that he paid 82% of the price, right?

since you can say that 82% is 0.82, so for the product BEFORE taxes he paid 0.82y

However, he also had to pay taxes, which is 8% or, it other words, he paid 108% for the game. Since 108% is 1.08, so for the game he paid "
\[(0.82*1.08)y=?\]
