Irene has $9 more than Elyse. Nicole has nine times as much money as Irene. They have a total of $189.
- How much money does Irene have?
- How much money does Nicole have?
(a)
Amount that Irene has = 1 u
Amount that Elyse has = 1 u - 9
Amount that Nicole has = 9 u
Total amount that they has
= 1 u + 1 u - 9 + 9 u
= 11 u - 9
11 u - 9 = 189
11 u = 189 + 9
11 u = 198
1 u = 198 ÷ 11 = 18
(b)
Amount that Nicole has
= 9 u
= 9 x 18
= $162
Answer(s): (a) $18; (b) $162
