Aaron spends
14 of his money on 3 stickers and 2 cards.
Each card costs four times as much as each sticker.
Let the price of 1 sticker be 1 u.
- Cost of 1 card = _____ u
- Amount that Aaron has spent = _____ u
- Amount that Aaron has left = _____ u
- Amount that Aaron has at first = _____ u
(a)
Change X times into units.
Cost of 1 sticker = 1 u
Cost of 1 card = 4 x 1 u = 4 u
(b)
Amount that Aaron 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 -
14 =
34 14 of his money = 11 u
34 of his money = 3 x 11 u = 33 u
Amount that Aaron has left = 33 u
(d)
Amount that Aaron has at first
= 11 u + 33 u
= 44 u
Answer(s): (a) 4; (b) 11; (c) 33; (d) 44
