Tina spent some of her money on a skirt, a pair of sneakers and some necklaces. She spent ¹₈ of her money and an additional $252 on a skirt. Next, she spent ⁵₇ of the remaining money and an additional $62 on a pair of sneakers. Finally, she spent ⁴₅ of what she had left on some necklaces and had $2 left. How much did Tina have at first?
Fraction of the money that she had left
= 1 - ⁴₅ 
= ¹₅

¹₅ of the money she had left = 2
⁵₅ of the money she had left = 5 x 2 = 10

Fraction of the remaining money excluding the additional $62 spent on a pair of sneakers
= 1 - ⁵₇
= ²₇

²₇ of the remaining money = 10 + 62 = 72
¹₇ of the remaining money = 72 ÷ 2 = 36
⁷₇ of the remaining money = 7 x 36 = 252

Fraction of the total money excluding the additional $252 spent on the skirt
= 1 - ¹₈
= ⁷₈

⁷₈ of total money = 252 + 252 = 504
¹₈ of total money = 504 ÷ 7 = 72
⁸₈ of total money = 8 x 72 = 576

Amount that Tina had at first = $576

Answer(s): $576
