Kylie and Gillian had the same amount of money at first. After Kylie gave $70 to her son, Gillian had 8 times as much money as Kylie. How much did Kylie have in the end?
|
Kylie |
Gillian |
Before |
1x8 = 8 u |
1x8 = 8 u |
Change |
- $70 |
|
After |
1 u |
8 u |
The amount that Gillian had at first and in the end remains unchanged. Make the amount that Gillian had the same. LCM of 1 and 8 is 8.
Amount that Kylie gave to her son
= 8 u - 1 u
= 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Amount that Kylie had in the end
= 1 u
= $70
Answer(s): $70
