Tom had $10.80 less than Caden. After Tom gave $2.40 to Caden, Caden would have five times as much money as Tom. How much money had Caden at first?
| |
Caden |
Tom |
| Before |
5 u - $2.40 |
1 u + $2.40 |
| Change |
+ $2.40 |
- $2.40 |
| After |
5 u |
1 u |
Tom had $10.80 less than Caden. If another $10.80 was given to Tom, Caden and Tom would have the same amount at first.
5 u - 2.40 = 1 u + 2.40 + 10.80
5 u - 1 u = 2.40 + 10.80 + 2.40
4 u = 15.60
1 u = 15.60 ÷ 4 = 3.90
Amount that Caden had at first
= 5 u - 2.40
= 5 x 3.90 + 2.40
= 19.50 + 2.40
= $21.90
Answer(s): $21.90
