The question has missing details. So, I'll solve using a general assumption.
Let one of the coordinates of the figure be

Let the scale factor be n
When dilated, the new figure is:


To return the image back to the original figure, the new scale factor mus be a reciprocal of the previous scale factor i.e. 
So:

Substitute n(x,y) for A';



Take for instance:

-- scale factor



To get A from A', using the analysis above


Answer:
Step-by-step explanation:
So we know they had got $22,553 which is 90% more than last year. With this information we know:
190% = $22,553
1% = $22,553/190
1% = $118.70
100% = $11870
So overall it would be $11870 which they had got last year
Answer:
=12x+28
Step-by-step explanation:
