Amount that Linda had = $912
Amount that Eric had
= 912 - 580
= $332
Total amount that Linda and Eric had
= 912 + 332
= $1244
Amount that Linda had in the end = 1 u
Amount that Eric had in the end = 3 u
Total amount that Linda and Eric had
= 1 u + 3 u
= 4 u
As Linda gave some money to Eric, the total amount that Eric and Linda had at first and in the end remains unchanged.
4 u = 1244
1 u = 1244 ÷ 4 = 311
Amount that Linda gave Eric
= 912 - 311
= $601
Answer(s): $601
