1 u |
Cody had $8.40 less than Vincent. If another $8.40 was given to Cody, Vincent and Cody would have the same amount at first.
5 u - 3.20 = 1 u + 3.20 + 8.40
5 u - 1 u = 3.20 + 8.40 + 3.20
4 u = 14.80
1 u = 14.80 ÷ 4 = 3.70
Amount that Vincent had at first
= 5 u - 3.20
= 5 x 3.70 + 3.20
= 18.50 + 3.20
= $21.70
Answer(s): $21.70
