Adam spends $6 for 1 sticker and 1 bead.
The cost of 1 sticker is
15 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 = 5 u
Total cost of the sticker and the bead
= 1 u + 5 u
= 6 u
6 u = 6
1 u = 6 ÷ 6 = 1
Cost of the bead
= 5 u
= 5 x 1
= $5
(b)
Cost of the sticker less than the bead
= 5 u - 1 u
= 4 u
= 4 x 1
= $4
Answer(s): (a) $5; (b) $4
