Amount that Gwen had = $830
Amount that Caden had
= 830 - 481
= $349
Total amount that Gwen and Caden had
= 830 + 349
= $1179
Amount that Gwen had in the end = 1 u
Amount that Caden had in the end = 2 u
Total amount that Gwen and Caden had
= 1 u + 2 u
= 3 u
As Gwen gave some money to Caden, the total amount that Caden and Gwen had at first and in the end remains unchanged.
3 u = 1179
1 u = 1179 ÷ 3 = 393
Amount that Gwen gave Caden
= 830 - 393
= $437
Answer(s): $437
