Fill in the blanks.
Asher spends
18 of his money on 4 buttons and 5 pencils.
Each pencil costs four times as much as each button.
Let the price of 1 button be 1 u.
- Cost of 1 pencil = _____ 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 button = 1 u
Cost of 1 pencil = 4 x 1 u = 4 u
(b)
Amount that Asher 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 -
18 =
78 18 of his money = 24 u
78 of his money = 7 x 24 u = 168 u
Amount that Asher has left = 168 u
(d)
Amount that Asher has at first
= 24 u + 168 u
= 192 u
Answer(s): (a) 4; (b) 24; (c) 168; (d) 192
