Adam spends $10 for 1 marble and 1 sticker.
The cost of 1 marble is
14 the cost of 1 sticker.
- How much is the sticker?
- How much is the sticker more than the marble?
(a)
Cost of the marble = 1 u
Cost of the sticker = 4 u
Total cost of the marble and the sticker
= 1 u + 4 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Cost of the sticker
= 4 u
= 4 x 2
= $8
(b)
Cost of the sticker more than the marble
= 4 u - 1 u
= 3 u
= 3 x 2
= $6
Answer(s): (a) $8; (b) $6
