I'm not sure how to solve the following problem. I don't think i have enough information.
Ali deposited $120 in her savings account. This represents 75% of the money she received for her birthday. She pent the rest of her money on a lego toy. How much did the lego cost?
Can someone explain how to solve this, please?

Let x = the amount of money she received for her birthday.
0.75x = 120
x = 120 / 0.75
x = $160
160  120 = 40
She spent $40 on the toy.
