14 of his money on 4 coins and 5 cards.
Each card costs five times as much as each coin.
Let the price of 1 coin be 1 u.
- Cost of 1 card = _____ u

(a)
Change X times into units.
Cost of 1 coin = 1 u
Cost of 1 card = 5 x 1 u = 5 u
(b)
Amount that Aqil has spent
= 4 x 1 u + 5 x 5 u
= 4 u + 25 u
= 29 u
(c)
Fraction of the money he has left
= 1 -
14 =
34 14 of his money = 29 u
34 of his money = 3 x 29 u = 87 u
Amount that Aqil has left = 87 u
(d)
