5 u |
1 u |
Elijah had $15.40 less than Ben. If another $15.40 was given to Elijah, Ben and Elijah would have the same amount at first.
5 u - 1.70 = 1 u + 1.70 + 15.40
5 u - 1 u = 1.70 + 15.40 + 1.70
4 u = 18.80
1 u = 18.80 ÷ 4 = 4.70
Amount that Ben had at first
= 5 u - 1.70
= 5 x 4.70 + 1.70
= 23.50 + 1.70
= $25.20
Answer(s): $25.20
