Xuan has $9 more than Natalie. Nicole has thrice as much money as Xuan. They have a total of $151.
- How much money does Xuan have?
- How much money does Nicole have?
(a)
Amount that Xuan has = 1 u
Amount that Natalie has = 1 u - 9
Amount that Nicole has = 3 u
Total amount that they has
= 1 u + 1 u - 9 + 3 u
= 5 u - 9
5 u - 9 = 151
5 u = 151 + 9
5 u = 160
1 u = 160 ÷ 5 = 32
(b)
Amount that Nicole has
= 3 u
= 3 x 32
= $96
Answer(s): (a) $32; (b) $96
