Three brothers spent a total of $70. Irene spent $6 more than Jade and Hazel spent $7 more than Irene.
- How much money did Jade spend?
- How much money did Hazel spend?
(a)
Amount that Jade spent = 1 u
Amount that Irene spent = 1 u + 6
Amount that Hazel spent = 1 u + 6 + 7 = 1 u + 13
Total amount that they spent
= 1 u + 1 u + 6 + 1 u + 13
= 3 u + 19
3 u + 19 = 70
3 u = 70 - 19
3 u = 51
1 u = 51 ÷ 3 = $17
Amount that Jade spent
= 1 u
= 17
(b)
Amount that Hazel spent
= 1 u + 13
= 17 + 13
= $30
Answer(s): (a) $17; (b) $30
