Suppose that you are a manager of a clothing store and have just purchased 100 shirts for $15 each. after a month of selling the shirts at the regular price, you plan to have a sale giving 30% of the original selling price. however ,you want to make a profit of $6 on each shirt at the sale price. what should you price the shirts at initially to ensure this?

He should set the original price at $27.30

When you say "Plan to have a sale giving 30% of the original selling price", I suppose it's taking away 30%? So taking away 30% is like $15 - $4.5 = $10.50
Adding $6 more is $16.50.
If you're saying the manager  is selling the price 30% of $15 then the price is $4.50 Plus the $6, it should be $10.50

So the answer should either be $16.50 or $10.50
               Hope this helps! :)
