Adam spends $6 for 1 marble and 1 sticker.
The cost of 1 marble is
12 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 = 2 u
Total cost of the marble and the sticker
= 1 u + 2 u
= 3 u
3 u = 6
1 u = 6 ÷ 3 = 2
Cost of the sticker
= 2 u
= 2 x 2
= $4
(b)
Cost of the sticker more than the marble
= 2 u - 1 u
= 1 u
= 1 x 2
= $2
Answer(s): (a) $4; (b) $2
