Esther has $6 more than Lucy. Zara has seven times as much money as Esther. They have a total of $120.
- How much money does Esther have?
- How much money does Zara have?
(a)
Amount that Esther has = 1 u
Amount that Lucy has = 1 u - 6
Amount that Zara has = 7 u
Total amount that they has
= 1 u + 1 u - 6 + 7 u
= 9 u - 6
9 u - 6 = 120
9 u = 120 + 6
9 u = 126
1 u = 126 ÷ 9 = 14
(b)
Amount that Zara has
= 7 u
= 7 x 14
= $98
Answer(s): (a) $14; (b) $98
