At a shop, Cathy paid $35 for 1 sticker and 5 cards. The sticker cost $5 more than each card.
- How much is 1 card?
- How much is 1 sticker?
(a)
Cost of 1 card = 1 u
Cost of 5 cards = 5 u
Cost of 1 sticker = 1 u + 5
Total cost of 1 sticker and 5 cards
= 5 u + 1 u + 5
= 6 u + 5
6 u + 5 = 35
6 u = 35 - 5
6 u = 30
1 u = 30 ÷ 6 = 5
Cost of 1 card
= 1 u
= $5
(b)
Cost of 1 sticker
= 1 u + 5
= 5 + 5
= $10
Answer(s): (a) $5; (b) $10
