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