Japheth had $9.80 less than Eric. After Japheth gave $1.30 to Eric, Eric would have five times as much money as Japheth. How much money had Eric at first?
| |
Eric |
Japheth |
| Before |
5 u - $1.30 |
1 u + $1.30 |
| Change |
+ $1.30 |
- $1.30 |
| After |
5 u |
1 u |
Japheth had $9.80 less than Eric. If another $9.80 was given to Japheth, Eric and Japheth would have the same amount at first.
5 u - 1.30 = 1 u + 1.30 + 9.80
5 u - 1 u = 1.30 + 9.80 + 1.30
4 u = 12.40
1 u = 12.40 ÷ 4 = 3.10
Amount that Eric had at first
= 5 u - 1.30
= 5 x 3.10 + 1.30
= 15.50 + 1.30
= $16.80
Answer(s): $16.80
