Since both Jack and Ivan spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 5 u - 1 u
= 4 u
4 u = 92
1 u = 92 ÷ 4 = 23
Amount that Jack had in the end
= 5 u
= 5 x 23
= $115
Amount that Jack had spent
= 178 - 115
= $63
Amount that each of them spent every day
= 63 ÷ 9
= $7
Answer(s): $7
