Adam spends $10 for 1 sticker and 1 bead.
The cost of 1 sticker is
14 the cost of 1 bead.
- How much is the bead?
- How much is the sticker less than the bead?
(a)
Cost of the sticker = 1 u
Cost of the bead = 4 u
Total cost of the sticker and the bead
= 1 u + 4 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Cost of the bead
= 4 u
= 4 x 2
= $8
(b)
Cost of the sticker less than the bead
= 4 u - 1 u
= 3 u
= 3 x 2
= $6
Answer(s): (a) $8; (b) $6
