Easy... :)
1,000= One thousand.
Thus, your answer. :D
On a phone here and no access to paper but you must first find the midpoint of AC which is the average of the coordinates. The perpendicular bisector will have a gradient that multiplies by AC's gradient to make -1. This will obviously pass through its mid point so as long as you know how to use y=mx+c you should be good.

Answer:
<em>Money in her purse is Rs. 500.</em>
<em></em>
Step-by-step explanation:
Let the money in her purse = Rs.
Let the money in her Money box = Rs.
As per question statement,
- Double the money in her purse (i.e. ) and add it to the amount in money box, she gets Rs. 1700.
........ (1)
- Triple the money in her purse (i.e. ) and add it to amount in money box (), she gets Rs. 2200.
....... (2)
<u>To find: </u>Money in her purse = ? i.e.
Let us solve for using the two linear equations.
We can use substitution method here i.e. find value of one variable from one equation and then substitute that value in other equation.
Using equation (1), we get the value of as follows:
Now, let us put this value of y in equation (2) to find the value of :
<em>Money in her purse is Rs. 500.</em>
