Answer:
64
Step-by-step explanation:
Lets take the total amount of money at beginning as x.
amount spent = (1/4)x + (1/8)x
LCM =8
terms = 2/8 + 1/8
=(3/8)x
leaving her with (5/8)x as 1 whole =(8/8)x so, (8/8)x -(3/8)x = (5/8)x
5x/8 = 40 (as she was left with $40)
5x = 40 x 8
5x = 320
x = 320/5
x= 64
