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?
