She payed $269 for the chainsaw :)
42.87*0.15= $6.43 rounded
Simplify for -5/8*2/3= -5/12
-0.416 as a mixed number
Rotation and translation are rigid transformations, they don't change figure sizes. Dilation change figure sizes increasing or decreasing them by scale factor.
First, find AB and A'B' by the formula:

As you can see AB=2A'B'. This means that the segment AB was decreased twice to form segment A'B'. Then the scale factor is 1/2.
