Since both Daniel and Reggie spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 3 u - 1 u
= 2 u
2 u = 42
1 u = 42 ÷ 2 = 21
Amount that Daniel had in the end
= 3 u
= 3 x 21
= $63
Amount that Daniel had spent
= 105 - 63
= $42
Amount that each of them spent every day
= 42 ÷ 6
= $7
Answer(s): $7
