| After |
3 u + $96.80 |
1 u |
2 u + $96.80 |
Rael had $109.40 more than Charlie in the end.
3 u + 96.80 - 1 u = 109.40
2 u + 96.80 = 109.40
2 u = 109.40 - 96.80
2 u = 12.60
1 u = 12.60 ÷ 2 = 6.30
Amount that Rael had at first
= 3 u + 96.80
= 3 x 6.30 + 96.80
= 18.90 + 96.80
= $115.70
Answer(s): $115.70
