Since both Peter and Jack 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 = 108
1 u = 108 ÷ 3 = 36
Amount that Peter had in the end
= 4 u
= 4 x 36
= $144
Amount that Peter had spent
= 224 - 144
= $80
Amount that each of them spent every day
= 80 ÷ 8
= $10
Answer(s): $10
