Three brothers spent a total of $77. Jean spent $9 more than Hilda and Winnie spent $8 more than Jean.
- How much money did Hilda spend?
- How much money did Winnie spend?
(a)
Amount that Hilda spent = 1 u
Amount that Jean spent = 1 u + 9
Amount that Winnie spent = 1 u + 9 + 8 = 1 u + 17
Total amount that they spent
= 1 u + 1 u + 9 + 1 u + 17
= 3 u + 26
3 u + 26 = 77
3 u = 77 - 26
3 u = 51
1 u = 51 ÷ 3 = $17
Amount that Hilda spent
= 1 u
= 17
(b)
Amount that Winnie spent
= 1 u + 17
= 17 + 17
= $34
Answer(s): (a) $17; (b) $34
