Since both Perry and Charlie spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 4 u - 1 u
= 3 u
3 u = 144
1 u = 144 ÷ 3 = 48
Amount that Perry had in the end
= 4 u
= 4 x 48
= $192
Amount that Perry had spent
= 207 - 192
= $15
Amount that each of them spent every day
= 15 ÷ 3
= $5
Answer(s): $5
