We may solve this problem by using proportions.
The reasoning would go like this: Let X be the original price of the desk. Since the discount was 25%, it means $25 saved per every $100. So, if Mark saved $25 per $100, he saved $45 for how much? Or 25 per 100, 45 per X. The proportion goes:

X = 180
The price of the desk, before the discount, was $180.
Since Mark got 25% discount, or $45, he paid 180 - 45, or $135.
