After 2 |

35 x 460= 276
460 - 276 = 184
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 276
=
25100 x 276
= 69
276 - 69 = 207
184 + 69 = 253
If Penelope received another $118 in the end, Penelope and Pamela would have the same amount of money.
6 u + 207 = 4 u + 253 + 118
6 u - 4 u = 253 + 118 - 207
2 u = 164
1 u = 164 ÷ 2 = 82
Amount that Pamela had at first
= 5 u
= 5 x 82
= $410
Answer(s): $410
