In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
two tickets price = $90
face value ticket price = $52.50
markdown = ?
percent markdown = ?
Step 02:
a. markdown
markdown = 2* face value ticket price - two tickets price
= 2 * $52.50 - 90$
= $105 - $90
= $15
Step 03:
b. percent markdown
percent markdown = ($15 / $105) * 100%
= 14.3%
The answer is:
markdown = $15
percent markdown = 14%
