Adam spends ¹₁₅ of his money on some beads.
He spends ²₅ of his money on some marbles and
²₃ of the remaining money on some stickers.
In the end, he has $48 left.

1. How much does he spend on the beads?
2. How much does he spend on the marbles?
3. How much does he spend on the stickers?
4. How much does he spend altogether?

(a)
Amount left after Adam spends on beads and marbles
= 1 - ¹₁₅ - ²₅
= 1 - ¹₁₅ - ⁶₁₅
= ⁸₁₅

Make the numerators the same.
⁸₁₅ of the amount = ³₃ of the remaining amount
²⁴₄₅ of the amount = ²⁴₂₄ of the remaining amount

Amount that Adam spends on beads = ¹₁₅ = ³₄₅ 
Amount that Adam spends on marbles = ²₅ = ¹⁸₄₅

Amount that Adam spends on stickers
= ²₃ x 24 u
= 16 u 

Amount that he has left
= 24 u - 16 u
= 8 u

8 u = 48

1 u = 48 ÷ 8 = 6

Amount that he spends on the beads
= 3 u
= 3 x 6
= $18

(b)
Amount that he spends on the marbles
= 18 u
= 18 x 6
= $108

(c)
Amount that he spends on the stickers
= 16 u
= 16 x 6
= $96

(d)
Amount that he spends altogether
= 18 + 108 + 96
= $222

Answer(s): (a) $18; (b) $108; (c) $96; (d) $222
