Jill spent 40% of her money . If she had €120 left , how much had she at the start ?

Answer 1

€120 x .40 = 48
120 + 48 = 168

Answer 2

So if she spent 40% of her money, she had 60% of her money left, which is 120
so .6x = 120
x = 120/.6 = 200

check:
40% of 200 = 80 leaving her with 120

Marie you took 40% of what she had left.
