Penelope has $6 more than Roshel. Xuan has nine times as much money as Penelope. They have a total of $115.
- How much money does Penelope have?
- How much money does Xuan have?
(a)
Amount that Penelope has = 1 u
Amount that Roshel has = 1 u - 6
Amount that Xuan has = 9 u
Total amount that they has
= 1 u + 1 u - 6 + 9 u
= 11 u - 6
11 u - 6 = 115
11 u = 115 + 6
11 u = 121
1 u = 121 ÷ 11 = 11
(b)
Amount that Xuan has
= 9 u
= 9 x 11
= $99
Answer(s): (a) $11; (b) $99
