Rael had $6.80 less than John. After Rael gave $2.80 to John, John would have five times as much money as Rael. How much money had John at first?

John |
Rael |
| Before |
5 u - $2.80 |
1 u + $2.80 |
| Change |
+ $2.80 |
- $2.80 |
| After |
5 u |
1 u |
Rael had $6.80 less than John. If another $6.80 was given to Rael, John and Rael would have the same amount at first.
5 u - 2.80 = 1 u + 2.80 + 6.80
5 u - 1 u = 2.80 + 6.80 + 2.80
4 u = 12.40
1 u = 12.40 ÷ 4 = 3.10
Amount that John had at first
= 5 u - 2.80
= 5 x 3.10 + 2.80
= 15.50 + 2.80
= $18.30
Answer(s): $18.30
