Answer:
The selling price of one cabinet is $ 506.90.
Explanation:
Let x be the cost price of one cabinet,
Given,
The markup percentage = 145%
Thus, the markup in one cabinet = 145 % of the cost price of one cabinet
= 145% of x


According to the question,
1.45x = 300

So, the cost price of one cabinet = $ 206.90 ( approx ),
Hence, the selling price of the cabinet = Cost price of the cabinet + Markup
= $ 206.90 + $ 300
= $ 506.90
