Since both Carl and Lee 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 = 69
1 u = 69 ÷ 3 = 23
Amount that Carl had in the end
= 4 u
= 4 x 23
= $92
Amount that Carl had spent
= 113 - 92
= $21
Amount that each of them spent every day
= 21 ÷ 7
= $3
Answer(s): $3
