Since both Julian and Vincent 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 = 144
1 u = 144 ÷ 4 = 36
Amount that Julian had in the end
= 5 u
= 5 x 36
= $180
Amount that Julian had spent
= 216 - 180
= $36
Amount that each of them spent every day
= 36 ÷ 9
= $4
Answer(s): $4
