<h2>Answer:</h2>
- No, the sale price was not correct.
The sale price should have been $ 13.60.
<h2>Step-by-step explanation:</h2>It was given that the T-shirt was on a sale with a discount of 15%.
This means that one have to pay (100-15)%=85% of the actual or regular price.
The regular price of the T-shirt was $16.00.
The cost of T-shirt after applying the advertised discount or offer will cost:
85% of 16
i.e.
Hence, the T-shirt will cost= $ 13.60
But it was given that it was on sale for $ 14≠ $ 13.60
Hence, the sale price was not correct.

Answer:
The result is the same.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- square 12 inches wide
- 3-inch diameter cookies are cut => its radius is: 1.5 inches
Hence we can find some information:
- The area of the square is:
square inches
- The area of a cookies is:
π = 3.14*
= 7.065 square inches
- The total number of 3-inch cookies are: 4*4 =16
=> The total area of the cookies is: 16* 7.065 = 113.04 square inches
=> how much cookie dough is "wasted" when 3-inch cookies are cut:
= The area of the square - The total area of the cookies
= 144 - 113.04 = 30.96 square inches
If the diameter is increased to 4 inches => its radius: 2 inches, we have:
- The area of a cookies is:
square inches
- The total number of 3-inch cookies are: 3*3 =9
=> The total area of the cookies is: 9* 12.56 = 113.04 square inches
=> how much cookie dough is "wasted" when 4-inch cookies are cut:
= The area of the square - The total area of the cookies
= 144 - 113.04 = 30.96 square inches
The result is the same.
