Zoe uses 1/3 of her money to buy a dress and 1/4 of the remaining

amount to buy some magazines. After that, she uses 2/5 of the rest

of the money to buy a present.

If she has $54 left, how much money did she spend on the magazines?

x - (x/3 + x/6 + x/5) = 54

 

x = 180

 

She spent on the magazines $30.

Set Zoe have x altogether,

Money for clothes : 1/3x

Money for magazines : (x - 1/3x) * 1/4

                                   = 1/6x

Money for gifts : (x - 1/3x - 1/6x) * 2/5 = 1/5x

        x - 1/3x - 1/6x - 1/5x = 54

                                  3/10x = 54    x = 180

 

Money for magazines = 1/6x = 180 * 1/6

                                              = 30
