Since Flynn had $200 less than Albert, this means Albert had $200 more than Flynn.
1 u - 190 = 1 p --- (1)
1 u + 200 + 120 = 4 p
1 u + 320 =
4 p --- (2)
Make p the same.
(1)
x4
4 u - 760 =
4 p --- (3)
(3) = (2)
4 u - 760 = 1 u + 320
4 u - 1 u = 320 + 760
3 u = 1080
1 u = 1080 ÷ 3 = 360
Total amount that Flynn and Albert had
= 1 u + 1 u + 200
= 2 u + 200
= 2 x 360 + 200
= 720 + 200
= $920
Answer(s): $920
