Natalie has $6 more than Sabrina. Jane has thrice as much money as Natalie. They have a total of $129.
- How much money does Natalie have?
- How much money does Jane have?
(a)
Amount that Natalie has = 1 u
Amount that Sabrina has = 1 u - 6
Amount that Jane has = 3 u
Total amount that they has
= 1 u + 1 u - 6 + 3 u
= 5 u - 6
5 u - 6 = 129
5 u = 129 + 6
5 u = 135
1 u = 135 ÷ 5 = 27
(b)
Amount that Jane has
= 3 u
= 3 x 27
= $81
Answer(s): (a) $27; (b) $81
