Yoko has $5 more than Barbara. Jane has six times as much money as Yoko. They have a total of $115.
- How much money does Yoko have?
- How much money does Jane have?
(a)
Amount that Yoko has = 1 u
Amount that Barbara has = 1 u - 5
Amount that Jane has = 6 u
Total amount that they has
= 1 u + 1 u - 5 + 6 u
= 8 u - 5
8 u - 5 = 115
8 u = 115 + 5
8 u = 120
1 u = 120 ÷ 8 = 15
(b)
Amount that Jane has
= 6 u
= 6 x 15
= $90
Answer(s): (a) $15; (b) $90
