Since both Peter 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 = 128
1 u = 128 ÷ 4 = 32
Amount that Peter had in the end
= 5 u
= 5 x 32
= $160
Amount that Peter had spent
= 192 - 160
= $32
Amount that each of them spent every day
= 32 ÷ 4
= $8
Answer(s): $8
