Answer:
The final price of money of t shirt that I own = $ 16.69
Explanation:
Given in question as ,
The t shirt cost to the owner = $12
The markup percentage = 30%
So, now the cost price of t shirt = 30% of 12 + 12
= 3.6 + 12 = $15.6
Tax which is added now = 7%
So, new cost of t shirt = 7% of 15.6 + 15.6
= 1.092 + 15.6 =$ 16.69
Hence , the final price of money of t shirt that I own = $ 16.69 Answer
