Since Will had $140 less than Harry, this means Harry had $140 more than Will.
1 u - 160 = 1 p --- (1)
1 u + 140 + 850 = 6 p
1 u + 990 =
6 p --- (2)
Make p the same.
(1)
x6
6 u - 960 =
6 p --- (3)
(3) = (2)
6 u - 960 = 1 u + 990
6 u - 1 u = 990 + 960
5 u = 1950
1 u = 1950 ÷ 5 = 390
Total amount that Will and Harry had
= 1 u + 1 u + 140
= 2 u + 140
= 2 x 390 + 140
= 780 + 140
= $920
Answer(s): $920
