15 Kathy and Victoria had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 1 and 4 is 4.
Amount that Kathy had less than Victoria at first
= 20 u - 5 u
= 15 u
15 u = 195
1 u = 195 ÷ 15 = 13
Amount that Victoria had at first
= 20 u
= 20 x 13
= $260
Answer(s): $260
