At a shop, Hazel paid $88 for 1 sticker and 5 cards. The sticker cost $4 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 + 4
Total cost of 1 sticker and 5 cards
= 5 u + 1 u + 4
= 6 u + 4
6 u + 4 = 88
6 u = 88 - 4
6 u = 84
1 u = 84 ÷ 6 = 14
Cost of 1 card
= 1 u
= $14
(b)
Cost of 1 sticker
= 1 u + 4
= 14 + 4
= $18
Answer(s): (a) $14; (b) $18
