Penelope has $12 more than Raeann. Yoko has eight times as much money as Penelope. They have a total of $168.
- How much money does Penelope have?
- How much money does Yoko have?
(a)
Amount that Penelope has = 1 u
Amount that Raeann has = 1 u - 12
Amount that Yoko has = 8 u
Total amount that they has
= 1 u + 1 u - 12 + 8 u
= 10 u - 12
10 u - 12 = 168
10 u = 168 + 12
10 u = 180
1 u = 180 ÷ 10 = 18
(b)
Amount that Yoko has
= 8 u
= 8 x 18
= $144
Answer(s): (a) $18; (b) $144
