After |
4 u + $44.20 |
1 u |
3 u + $44.20 |
Gabriel had $69.10 more than Billy in the end.
4 u + 44.20 - 1 u = 69.10
3 u + 44.20 = 69.10
3 u = 69.10 - 44.20
3 u = 24.90
1 u = 24.90 ÷ 3 = 8.30
Amount that Gabriel had at first
= 4 u + 44.20
= 4 x 8.30 + 44.20
= 33.20 + 44.20
= $77.40
Answer(s): $77.40
