Amount that Tammy had = $927
Amount that Peter had
= 927 - 405
= $522
Total amount that Tammy and Peter had
= 927 + 522
= $1449
Amount that Tammy had in the end = 1 u
Amount that Peter had in the end = 2 u
Total amount that Tammy and Peter had
= 1 u + 2 u
= 3 u
As Tammy gave some money to Peter, the total amount that Peter and Tammy had at first and in the end remains unchanged.
3 u = 1449
1 u = 1449 ÷ 3 = 483
Amount that Tammy gave Peter
= 927 - 483
= $444
Answer(s): $444
