Natalie has 4 cards fewer than Hazel but 41 cards more than Sean. The three children have 149 cards altogether.
- How many cards does Sean have?
- How many cards does Hazel have?
(a)
Number of cards Hazel has = 1 u
Number of cards Natalie has = 1 u - 4
Number of cards Sean has = 1 u - 4 - 41 = 1 u - 45
Total number of cards
= 1 u + 1 u - 4 + 1 u - 45
= 3 u - 49
3 u - 49 = 149
3 u = 149 + 49
3 u = 198
1 u = 198 ÷ 3 = 66
Number of cards that Sean has
= 1 u - 45
= 66 - 45
= 21
(b)
Number of cards that Hazel has
= 1 u
= 66
Answer(s): (a) 21; (b) 66
