Since Flynn had $180 less than Valen, this means Valen had $180 more than Flynn.
1 u - 110 = 1 p --- (1)
1 u + 180 + 630 = 5 p
1 u + 810 =
5 p --- (2)
Make p the same.
(1)
x5
5 u - 550 =
5 p --- (3)
(3) = (2)
5 u - 550 = 1 u + 810
5 u - 1 u = 810 + 550
4 u = 1360
1 u = 1360 ÷ 4 = 340
Total amount that Flynn and Valen had
= 1 u + 1 u + 180
= 2 u + 180
= 2 x 340 + 180
= 680 + 180
= $860
Answer(s): $860
