<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.

Given:
Consider the two points are B(2,3) and B'(-4,-6).
Center of dilation is the origin.
To find:
The scale factors of this dilation that transformed B into B'.
Solution:
If a figure dilatated by scale factor k and center of dilation is the origin, then
It means, the point after dilation is
where, k is the scale factor.
x-coordinate of image is -4 and x-coordinate of original point is 2.
Therefore, the scale factor is -2. It means, the point and image lie on the opposite sides of center of dilation.
