- 5 u |

| After |
6 u + $42.30 |
1 u |
5 u + $42.30 |
Rael had $82.80 more than Valen in the end.
6 u + 42.30 - 1 u = 82.80
5 u + 42.30 = 82.80
5 u = 82.80 - 42.30
5 u = 40.50
1 u = 40.50 ÷ 5 = 8.10
Amount that Rael had at first
= 6 u + 42.30
= 6 x 8.10 + 42.30
= 48.60 + 42.30
= $90.90
Answer(s): $90.90
