35 x 120= 72
120 - 72 = 48
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 72
=
25100 x 72
= 18
72 - 18 = 54
48 + 18 = 66
If Tiffany received another $238 in the end, Tiffany and Raeann would have the same amount of money.
6 u + 54 = 4 u + 66 + 238
6 u - 4 u = 66 + 238 - 54
2 u = 250
1 u = 250 ÷ 2 = 125
Amount that Raeann had at first
= 5 u
= 5 x 125
= $625
Answer(s): $625
