Adam spends ¹₁₀ of his money on some beads.
He spends ³₅ of his money on some stickers and
³₄ of the remaining money on some marbles.
In the end, he has $36 left.

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

(a)
Amount left after Adam spends on beads and stickers
= 1 - ¹₁₀ - ³₅
= 1 - ¹₁₀ - ⁶₁₀
= ³₁₀

Make the numerators the same.
³₁₀ of the amount = ⁴₄ of the remaining amount
¹²₄₀ of the amount = ¹²₁₂ of the remaining amount

Amount that Adam spends on beads = ¹₁₀ = ⁴₄₀ 
Amount that Adam spends on stickers = ³₅ = ²⁴₄₀

Amount that Adam spends on marbles
= ³₄ x 12 u
= 9 u 

Amount that he has left
= 12 u - 9 u
= 3 u

3 u = 36

1 u = 36 ÷ 3 = 12

Amount that he spends on the beads
= 4 u
= 4 x 12
= $48

(b)
Amount that he spends on the stickers
= 24 u
= 24 x 12
= $288

(c)
Amount that he spends on the marbles
= 9 u
= 9 x 12
= $108

(d)
Amount that he spends altogether
= 48 + 288 + 108
= $444

Answer(s): (a) $48; (b) $288; (c) $108; (d) $444
