Answer:
1. $8.55
2. $4.29
3. $17.00
4. $10.47
5. $40.31
Step-by-step explanation:
First, you need to divide 12.5/2.5= 5. After that, you need to multiply 17.50x5=87.50. So your answer is $87.50.
Applying a dilation centered at the origin with scale factor 
has the effect of multiplying both coordinates of a point by :
So, in your case, the coordinates of the points double:
4a-9b=22
substitute b=-2
4a -9(-2) = 22
4a +18 =22
subtract 18 from each side
4a = 4
divide by 4
a =1
