Adam spends ¹₉ of his money on some marbles.
He spends ²₃ of his money on some stickers and
³₅ of the remaining money on some beads.
In the end, he has $24 left.

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

(a)
Amount left after Adam spends on marbles and stickers
= 1 - ¹₉ - ²₃
= 1 - ¹₉ - ⁶₉
= ²₉

Make the numerators the same.
²₉ of the amount = ⁵₅ of the remaining amount
¹⁰₄₅ of the amount = ¹⁰₁₀ of the remaining amount

Amount that Adam spends on marbles = ¹₉ = ⁵₄₅ 
Amount that Adam spends on stickers = ²₃ = ³⁰₄₅

Amount that Adam spends on beads
= ³₅ x 10 u
= 6 u 

Amount that he has left
= 10 u - 6 u
= 4 u

4 u = 24

1 u = 24 ÷ 4 = 6

Amount that he spends on the marbles
= 5 u
= 5 x 6
= $30

(b)
Amount that he spends on the stickers
= 30 u
= 30 x 6
= $180

(c)
Amount that he spends on the beads
= 6 u
= 6 x 6
= $36

(d)
Amount that he spends altogether
= 30 + 180 + 36
= $246

Answer(s): (a) $30; (b) $180; (c) $36; (d) $246
