Amount that Eva had = $854
Amount that Simon had
= 854 - 430
= $424
Total amount that Eva and Simon had
= 854 + 424
= $1278
Amount that Eva had in the end = 1 u
Amount that Simon had in the end = 5 u
Total amount that Eva and Simon had
= 1 u + 5 u
= 6 u
As Eva gave some money to Simon, the total amount that Simon and Eva had at first and in the end remains unchanged.
6 u = 1278
1 u = 1278 ÷ 6 = 213
Amount that Eva gave Simon
= 854 - 213
= $641
Answer(s): $641
