After |
7 u + $84.30 |
1 u |
6 u + $84.30 |
Eric had $107.70 more than Daniel in the end.
7 u + 84.30 - 1 u = 107.70
6 u + 84.30 = 107.70
6 u = 107.70 - 84.30
6 u = 23.40
1 u = 23.40 ÷ 6 = 3.90
Amount that Eric had at first
= 7 u + 84.30
= 7 x 3.90 + 84.30
= 27.30 + 84.30
= $111.60
Answer(s): $111.60
