Since Japheth had $140 less than Flynn, this means Flynn had $140 more than Japheth.
1 u - 130 = 1 p --- (1)
1 u + 140 + 850 = 5 p
1 u + 990 =
5 p --- (2)
Make p the same.
(1)
x5
5 u - 650 =
5 p --- (3)
(3) = (2)
5 u - 650 = 1 u + 990
5 u - 1 u = 990 + 650
4 u = 1640
1 u = 1640 ÷ 4 = 410
Total amount that Japheth and Flynn had
= 1 u + 1 u + 140
= 2 u + 140
= 2 x 410 + 140
= 820 + 140
= $960
Answer(s): $960
