Cindy has $4 more than Tina. Natalie has twice as much money as Cindy. They have a total of $128.
- How much money does Cindy have?
- How much money does Natalie have?
(a)
Amount that Cindy has = 1 u
Amount that Tina has = 1 u - 4
Amount that Natalie has = 2 u
Total amount that they has
= 1 u + 1 u - 4 + 2 u
= 4 u - 4
4 u - 4 = 128
4 u = 128 + 4
4 u = 132
1 u = 132 ÷ 4 = 33
(b)
Amount that Natalie has
= 2 u
= 2 x 33
= $66
Answer(s): (a) $33; (b) $66
