Since both Brandon and Howard 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 = 42
1 u = 42 ÷ 1 = 42
Amount that Brandon had in the end
= 2 u
= 2 x 42
= $84
Amount that Brandon had spent
= 112 - 84
= $28
Amount that each of them spent every day
= 28 ÷ 4
= $7
Answer(s): $7
