Tim had $5.80 less than Rael. After Tim gave $1.90 to Rael, Rael would have four times as much money as Tim. How much money had Rael at first?
| |
Rael |
Tim |
| Before |
4 u - $1.90 |
1 u + $1.90 |
| Change |
+ $1.90 |
- $1.90 |
| After |
4 u |
1 u |
Tim had $5.80 less than Rael. If another $5.80 was given to Tim, Rael and Tim would have the same amount at first.
4 u - 1.90 = 1 u + 1.90 + 5.80
4 u - 1 u = 1.90 + 5.80 + 1.90
3 u = 9.60
1 u = 9.60 ÷ 3 = 3.20
Amount that Rael had at first
= 4 u - 1.90
= 4 x 3.20 + 1.90
= 12.80 + 1.90
= $14.70
Answer(s): $14.70
