Cost of Minecraft Dungeons = x

Amount of discount on Minecraft Dungeons = 30% of x

Amount of discount = \frac{30}{100}*x

Amount of discount = 0.3x

Total cost of Minecraft Dungeons = Total cost - Discount

Total cost of Minecraft Dungeons = x - 0.3x

Hence,

The expression x-0.3x represents the total cost of Minecraft Dungeons.
