- 7 u |

| After |
8 u + $45.90 |
1 u |
7 u + $45.90 |
Japheth had $117.30 more than Paul in the end.
8 u + 45.90 - 1 u = 117.30
7 u + 45.90 = 117.30
7 u = 117.30 - 45.90
7 u = 71.40
1 u = 71.40 ÷ 7 = 10.20
Amount that Japheth had at first
= 8 u + 45.90
= 8 x 10.20 + 45.90
= 81.60 + 45.90
= $127.50
Answer(s): $127.50
