Jen, Eva and Xandra shared $546 among themselves. Eva and Xandra shared
27 of the money equally. After Eva gave away some of her money to Jen, Xandra had 3 times as much money as Eva. How much money did Eva give to Jen?

Eva |
Xandra |
Jen |
Total |
Before |
1x3 = 3 u |
1x3 = 3 u |
5x3 = 15 u |
21 u |
Change |
- 2 u |
No change |
+ 2 u |
|
After |
1x1 = 1 u |
3x1 = 3 u |
17 u |
21 u |
Eva and Xandra shared
27 of the money equally.
Fraction of the money that Eva and Xandra each had
=
27 ÷ 2
=
27 x
12 =
17 The amount that Xandra had remains unchanged. The amount that Xandra had is the unchanged quantity. Make the amount that Xandra had the same. LCM of 1 and 3 is 3.
The amount that Eva and Xandra had at first is the same.
Total amount that they had at first
= 3 u + 3 u + 15 u
= 21 u
21 u = 546
1 u = 546 ÷ 21 = 26
Amount that Eva gave to Jen
= 3 u - 1 u
= 2 u
= 2 x 26
= $52
Answer(s): $52
