Xavier had $3.40 less than Tim. After Xavier gave $2.50 to Tim, Tim would have thrice as much money as Xavier. How much money had Tim at first?
| |
Tim |
Xavier |
| Before |
3 u - $2.50 |
1 u + $2.50 |
| Change |
+ $2.50 |
- $2.50 |
| After |
3 u |
1 u |
Xavier had $3.40 less than Tim. If another $3.40 was given to Xavier, Tim and Xavier would have the same amount at first.
3 u - 2.50 = 1 u + 2.50 + 3.40
3 u - 1 u = 2.50 + 3.40 + 2.50
2 u = 8.40
1 u = 8.40 ÷ 2 = 4.20
Amount that Tim had at first
= 3 u - 2.50
= 3 x 4.20 + 2.50
= 12.60 + 2.50
= $15.10
Answer(s): $15.10
