Fred had $3.20 less than Japheth. After Fred gave $2.50 to Japheth, Japheth would have thrice as much money as Fred. How much money had Japheth at first?
| |
Japheth |
Fred |
| Before |
3 u - $2.50 |
1 u + $2.50 |
| Change |
+ $2.50 |
- $2.50 |
| After |
3 u |
1 u |
Fred had $3.20 less than Japheth. If another $3.20 was given to Fred, Japheth and Fred would have the same amount at first.
3 u - 2.50 = 1 u + 2.50 + 3.20
3 u - 1 u = 2.50 + 3.20 + 2.50
2 u = 8.20
1 u = 8.20 ÷ 2 = 4.10
Amount that Japheth had at first
= 3 u - 2.50
= 3 x 4.10 + 2.50
= 12.30 + 2.50
= $14.80
Answer(s): $14.80
