Amount that Tammy had = $997
Amount that Ken had
= 997 - 581
= $416
Total amount that Tammy and Ken had
= 997 + 416
= $1413
Amount that Tammy had in the end = 1 u
Amount that Ken had in the end = 2 u
Total amount that Tammy and Ken had
= 1 u + 2 u
= 3 u
As Tammy gave some money to Ken, the total amount that Ken and Tammy had at first and in the end remains unchanged.
3 u = 1413
1 u = 1413 ÷ 3 = 471
Amount that Tammy gave Ken
= 997 - 471
= $526
Answer(s): $526
