Adam spends $7 for 1 bead and 1 sticker.
The cost of 1 bead is
34 the cost of 1 sticker.
- How much is the sticker?
- How much is the bead less than the sticker?
(a)
Cost of the bead = 3 u
Cost of the sticker = 4 u
Total cost of the bead and the sticker
= 3 u + 4 u
= 7 u
7 u = 7
1 u = 7 ÷ 7 = 1
Cost of the sticker
= 4 u
= 4 x 1
= $4
(b)
Cost of the bead less than the sticker
= 4 u - 3 u
= 1 u
= 1 x 1
= $1
Answer(s): (a) $4; (b) $1
