Amount that Tina had = $806
Amount that Paul had
= 806 - 628
= $178
Total amount that Tina and Paul had
= 806 + 178
= $984
Amount that Tina had in the end = 1 u
Amount that Paul had in the end = 2 u
Total amount that Tina and Paul had
= 1 u + 2 u
= 3 u
As Tina gave some money to Paul, the total amount that Paul and Tina had at first and in the end remains unchanged.
3 u = 984
1 u = 984 ÷ 3 = 328
Amount that Tina gave Paul
= 806 - 328
= $478
Answer(s): $478
