Answer:
Step-by-step explanation:
let CP=x Rs
3 % of x=9
x=9×100÷3=300
CP=300 Rs.
profit=6%
SP=300×106÷100=318 Rs
when profit =9%
SP=300×109÷100=327 Rs
It would be 5 months because if you do 75 + 20x = 35x
15x = 75
----- ------
15 15
x = 5
Answer: Choice A

========================================================
Work Shown:










Given:
A coordinate pair was dilated from (-3, 2) to (-6, 4).
To find:
The scale factor.
Solution:
We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.
The value of scale factor is:



Therefore, the scale factor is 2.
The answer is:
7 miles
5+2=7
