Dylan had $2.80 less than Oliver. After Dylan gave $2.20 to Oliver, Oliver would have four times as much money as Dylan. How much money had Oliver at first?

| Before |
4 u - $2.20 |
1 u + $2.20 |

| After |
4 u |
1 u |
Dylan had $2.80 less than Oliver. If another $2.80 was given to Dylan, Oliver and Dylan would have the same amount at first.
4 u - 2.20 = 1 u + 2.20 + 2.80
4 u - 1 u = 2.20 + 2.80 + 2.20
3 u = 7.20
1 u = 7.20 ÷ 3 = 2.40
Amount that Oliver had at first
= 4 u - 2.20
= 4 x 2.40 + 2.20
= 9.60 + 2.20
= $11.80
Answer(s): $11.80
