Since both Peter and Jeremy 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 = 78
1 u = 78 ÷ 3 = 26
Amount that Peter had in the end
= 4 u
= 4 x 26
= $104
Amount that Peter had spent
= 140 - 104
= $36
Amount that each of them spent every day
= 36 ÷ 6
= $6
Answer(s): $6
