Aqil spends
15 of his money on 3 marbles and 2 beads.
Each bead costs four times as much as each marble.
Let the price of 1 marble be 1 u.
- Cost of 1 bead = _____ u
- Amount that Aqil has spent = _____ u
- Amount that Aqil has left = _____ u
- Amount that Aqil has at first = _____ u
(a)
Change X times into units.
Cost of 1 marble = 1 u
Cost of 1 bead = 4 x 1 u = 4 u
(b)
Amount that Aqil has spent
= 3 x 1 u + 2 x 4 u
= 3 u + 8 u
= 11 u
(c)
Fraction of the money he has left
= 1 -
15 =
45 15 of his money = 11 u
45 of his money = 4 x 11 u = 44 u
Amount that Aqil has left = 44 u
(d)
Amount that Aqil has at first
= 11 u + 44 u
= 55 u
Answer(s): (a) 4; (b) 11; (c) 44; (d) 55
