Adam spends $7 for 1 sticker and 1 bead.
The cost of 1 sticker is
25 the cost of 1 bead.
- How much is the bead?
- How much is the sticker less than the bead?
(a)
Cost of the sticker = 2 u
Cost of the bead = 5 u
Total cost of the sticker and the bead
= 2 u + 5 u
= 7 u
7 u = 7
1 u = 7 ÷ 7 = 1
Cost of the bead
= 5 u
= 5 x 1
= $5
(b)
Cost of the sticker less than the bead
= 5 u - 2 u
= 3 u
= 3 x 1
= $3
Answer(s): (a) $5; (b) $3
