Eva has $12 more than Winnie. Kylie has eight times as much money as Eva. They have a total of $168.
- How much money does Eva have?
- How much money does Kylie have?
(a)
Amount that Eva has = 1 u
Amount that Winnie has = 1 u - 12
Amount that Kylie 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 Kylie has
= 8 u
= 8 x 18
= $144
Answer(s): (a) $18; (b) $144
