At a shop, Roshel paid $33 for 1 button and 4 stickers. The button cost $8 more than each sticker.
- How much is 1 sticker?
- How much is 1 button?
(a)
Cost of 1 sticker = 1 u
Cost of 4 stickers = 4 u
Cost of 1 button = 1 u + 8
Total cost of 1 button and 4 stickers
= 4 u + 1 u + 8
= 5 u + 8
5 u + 8 = 33
5 u = 33 - 8
5 u = 25
1 u = 25 ÷ 5 = 5
Cost of 1 sticker
= 1 u
= $5
(b)
Cost of 1 button
= 1 u + 8
= 5 + 8
= $13
Answer(s): (a) $5; (b) $13
