At a shop, Linda paid $14 for 1 stamp and 2 beads. The stamp cost $5 more than each bead.
- How much is 1 bead?
- How much is 1 stamp?
(a)
Cost of 1 bead = 1 u
Cost of 2 beads = 2 u
Cost of 1 stamp = 1 u + 5
Total cost of 1 stamp and 2 beads
= 2 u + 1 u + 5
= 3 u + 5
3 u + 5 = 14
3 u = 14 - 5
3 u = 9
1 u = 9 ÷ 3 = 3
Cost of 1 bead
= 1 u
= $3
(b)
Cost of 1 stamp
= 1 u + 5
= 3 + 5
= $8
Answer(s): (a) $3; (b) $8
