mark up is equivalent to increase.
The question says 180%X = 45. What is (200%-180%)X, or what is 20%X?

read it actively (start thinking mentally as you read the problem) & you will not have any problem what so ever..

A retailer bought a shirt at wholesale (X) and marked it up 80% (marked it up 80%, i.e. 180X/100)to its initial retail price of $45 (hmm, so that means 180X/100 = 45). By how many more dollars does he need to increase the price to achieve a 100% (what is 200X/100)markup?

Once you read it this way, you will know that you need to find
first, X
Then 2X
& then 1.8X is to be substracted to get the annswer as out of 2X, 1.8X increase has already been done.

Hope this helps.

I agree with the poster the question is not correctly worded and it should read "marked it up 80% of its initial retail price to $45" otherwise one can easily read the Q as saying that the 80% markup happened on the original price of $45
