Fill in the blanks.
Asher spends
16 of his money on 4 coins and 4 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
- Amount that Asher has spent = _____ u
- Amount that Asher has left = _____ u
- Amount that Asher has at first = _____ 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 Asher has spent
= 4 x 1 u + 4 x 5 u
= 4 u + 20 u
= 24 u
(c)
Fraction of the money he has left
= 1 -
16 =
56 16 of his money = 24 u
56 of his money = 5 x 24 u = 120 u
Amount that Asher has left = 120 u
(d)
Amount that Asher has at first
= 24 u + 120 u
= 144 u
Answer(s): (a) 5; (b) 24; (c) 120; (d) 144
