Since both Perry and Eric spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 2 u - 1 u
= 1 u
1 u = 34
1 u = 34 ÷ 1 = 34
Amount that Perry had in the end
= 2 u
= 2 x 34
= $68
Amount that Perry had spent
= 100 - 68
= $32
Amount that each of them spent every day
= 32 ÷ 4
= $8
Answer(s): $8
