Joelle has $8 more than Irene. Shannon has nine times as much money as Joelle. They have a total of $135.
- How much money does Joelle have?
- How much money does Shannon have?
(a)
Amount that Joelle has = 1 u
Amount that Irene has = 1 u - 8
Amount that Shannon has = 9 u
Total amount that they has
= 1 u + 1 u - 8 + 9 u
= 11 u - 8
11 u - 8 = 135
11 u = 135 + 8
11 u = 143
1 u = 143 ÷ 11 = 13
(b)
Amount that Shannon has
= 9 u
= 9 x 13
= $117
Answer(s): (a) $13; (b) $117
