Fiona and Xylia had the same amount of money at first. After Fiona gave $120 to her daughter, Xylia had 4 times as much money as Fiona. How much did Fiona have in the end?
| |
Fiona |
Xylia |
| Before |
1x4 =
4 u |
1x4 =
4 u |
| Change |
- $120 |
|
| After |
1 u |
4 u |
The amount that Xylia had at first and in the end remains unchanged. Make the amount that Xylia had the same. LCM of 1 and 4 is 4.
Amount that Fiona gave to her daughter
= 4 u - 1 u
= 3 u
3 u = 120
1 u = 120 ÷ 3 = 40
Amount that Fiona had in the end
= 1 u
= $120
Answer(s): $120
