Tina spent some of her money on a blouse, a pair of canvas shoes and some rings. She spent ¹₆ of her money and an additional $263 on a blouse. Next, she spent ³₈ of the remaining money and an additional $20 on a pair of canvas shoes. Finally, she spent ⁴₅ of what she had left on some rings and had $10 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 = 10
⁵₅ of the money she had left = 5 x 10 = 50

Fraction of the remaining money excluding the additional $20 spent on a pair of canvas shoes
= 1 - ³₈
= ⁵₈

⁵₈ of the remaining money = 50 + 20 = 70
¹₈ of the remaining money = 70 ÷ 5 = 14
⁸₈ of the remaining money = 8 x 14 = 112

Fraction of the total money excluding the additional $263 spent on the blouse
= 1 - ¹₆
= ⁵₆

⁵₆ of total money = 112 + 263 = 375
¹₆ of total money = 375 ÷ 5 = 75
⁶₆ of total money = 6 x 75 = 450

Amount that Tina had at first = $450

Answer(s): $450
