Since both Bobby and Dylan 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 = 136
1 u = 136 ÷ 4 = 34
Amount that Bobby had in the end
= 5 u
= 5 x 34
= $170
Amount that Bobby had spent
= 212 - 170
= $42
Amount that each of them spent every day
= 42 ÷ 6
= $7
Answer(s): $7
