Step-by-step explanation:

firstiful the correct version of the question is: " Nina spends 40% of her birthday money on a bracelet and 1/2 of the remainder on perfume.

She has $16.50 left. How much birthday money did she have in the first place?"

So if we take X as the money she recieved then:

0.6x-0.3x=16.50

0.3x=16.50

x=55
