Since both Albert and Elijah 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 = 45
1 u = 45 ÷ 1 = 45
Amount that Albert had in the end
= 2 u
= 2 x 45
= $90
Amount that Albert had spent
= 162 - 90
= $72
Amount that each of them spent every day
= 72 ÷ 9
= $8
Answer(s): $8
