Aqil spends
110 of his money on 4 stickers and 5 buttons.
Each button costs four times as much as each sticker.
Let the price of 1 sticker be 1 u.
- Cost of 1 button = _____ 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 sticker = 1 u
Cost of 1 button = 4 x 1 u = 4 u
(b)
Amount that Aqil has spent
= 4 x 1 u + 5 x 4 u
= 4 u + 20 u
= 24 u
(c)
Fraction of the money he has left
= 1 -
110 =
910 110 of his money = 24 u
910 of his money = 9 x 24 u = 216 u
Amount that Aqil has left = 216 u
(d)
Amount that Aqil has at first
= 24 u + 216 u
= 240 u
Answer(s): (a) 4; (b) 24; (c) 216; (d) 240
