$2500/2 = 1250. 1250/2 = 625. 625/2 = 312.5. 312.5/2 = 156.25. 156.25/2 = 78.125. 78.125/2 = 39.0625 Add all the end numbers up = 2460.9375. 2460.9375/2 = 1230.46875. 2460.9375 - 1230.46875 = 1230.46875. Therefore, she payed back 1230.46875, meaning she had 1230.46875 left in her account. Hope i helped! :D

5x -2y = -10 .....1
3x + 6y =66......2
on multiplying eq. 1 by 3
5x -2y = -10 .....1 ×3
15x -6y =-30
now subtract both equations ,
15x -6y =-30
3x + 6y =66
-___-_____-_
12x =-96
x= -8.
putting value of x in eq 1
5×8 -2y =-10
40 -2y =-10
40-10=2y
50=2y
25=y.
