23 x 135= 90
135 - 90 = 45
20% x 5 u
=
20100 x 5 u
= 1 u
20% x 90
=
20100 x 90
= 18
90 - 18 = 72
45 + 18 = 63
If Fanny received another $203 in the end, Fanny and Hazel would have the same amount of money.
4 u + 72 = 2 u + 63 + 203
4 u - 2 u = 63 + 203 - 72
2 u = 194
1 u = 194 ÷ 2 = 97
Amount that Fanny had at first
= 3 u + 135
= 3 x 97 + 135
= 291 + 135
= $426
Answer(s): $426
