After |
8 u + $64.50 |
1 u |
7 u + $64.50 |
Elijah had $149.20 more than Cole in the end.
8 u + 64.50 - 1 u = 149.20
7 u + 64.50 = 149.20
7 u = 149.20 - 64.50
7 u = 84.70
1 u = 84.70 ÷ 7 = 12.10
Amount that Elijah had at first
= 8 u + 64.50
= 8 x 12.10 + 64.50
= 96.80 + 64.50
= $161.30
Answer(s): $161.30
