Since both Carl and Mark 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 = 140
1 u = 140 ÷ 4 = 35
Amount that Carl had in the end
= 5 u
= 5 x 35
= $175
Amount that Carl had spent
= 207 - 175
= $32
Amount that each of them spent every day
= 32 ÷ 4
= $8
Answer(s): $8
