Ivory has $7 more than Hazel. Emily has twice as much money as Ivory. They have a total of $149.
- How much money does Ivory have?
- How much money does Emily have?
(a)
Amount that Ivory has = 1 u
Amount that Hazel has = 1 u - 7
Amount that Emily has = 2 u
Total amount that they has
= 1 u + 1 u - 7 + 2 u
= 4 u - 7
4 u - 7 = 149
4 u = 149 + 7
4 u = 156
1 u = 156 ÷ 4 = 39
(b)
Amount that Emily has
= 2 u
= 2 x 39
= $78
Answer(s): (a) $39; (b) $78
