The solution to this problem is trial and error. You know that if you have a total cost of purchasing one of each item, it will be $29.46 more than the total cost.
Add the three items before markup or markdown = $112.75+$76.85+$134.50+$89.65 = $423.75
So, apply markup to the leather jacket, blazer and wristwatch and apply mark down to the boots and you will get.
$112.75(1.25) + $76.85(1.25) + $134.50(1-0.30) + $89.65(1.25) = $443.21
For anyone who still needs this, it is actually C. boots.
Just had this on my quiz :)
