What is the scale factor from Figure A to Figure B?

Scale factor = 2

Explanation:

Pick on any pair of corresponding sides. I'll pick the right-most sides of each figure. For figure A, that would be the side of 40 units. Figure B has this corresponding side be 80 units long.

The scale factor is 80/40 = 2. This shows that figure B has sides 2 times longer compared to the corresponding sides on figure A.

So in short all you do is divide the corresponding side lengths. We divide in the format (figureB)/(figureA) because of the transition from A to B, and not the other way around.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
